The present disclosure provides a children's first aid kit suitable
for treating minor scrapes and cuts. The compact kit is integral
with a reusable cooling mechanism designed to provide a cooling
sensation to the injured area. The kit is further integral with
a supply of antiseptic medicine and bandages, and can be easily
carried and made available in any situation. An optional applicator
to dye the skin surrounding the wound to create a temporary design
can be supplied
A first aid adhesive plaster includes an adhesive sheet, a pad
member stuck onto the center of the adhesive sheet, and release
papers, which are releasably stuck to the adhesive sheet and cover
the pad member. The pad member comprises a pad made of a gauze,
an unwoven fabric, a woven fabric or the like, and a ultraviolet
blocking film disposed inside the pad or on the lower surface thereof.
The pad member may be wrapped with a net.
A first aid organizer kit assembly hitched onto posts of the head
rest of the driver's seat of a vehicle so that in the event of an
emergency first aid articles are then readily available. The assembly
includes a roll formed by a coilable organizer panel having an array
of pockets which accommodate a collection of first aid articles,
the panel being wound to create a loaded roll in which the articles
are embedded. The loaded roll is nested in a pouch that is attachable
to a mounting strip linked to the posts of the head rest so that
the strip then lies against the rear of the driver's seat. Should
an emergency arise, the pouch is detached from the mounting strip
and the roll is taken out of the pouch and unwound to make available
the first aid articles.
A solenoid valve includes a moving part, a plunger of magnetic
material having one end facing an end face of the moving part, and
a protrusion formed at the one end of the plunger and abutting on
the end face of the moving part. During energization, a magnetic
path is formed from a valve body to the moving part to produce an
attraction force between the valve body and the moving part across
a clearance. Magnetic flux running along the magnetic path becomes
saturated at the protrusion.
A solenoid valve has a solenoid, a control valve having a spool,
a seat member having an oil hole whose one end communicates with
a control pressure chamber between the seat member and the spool,
a supply passage through which a second supply port communicates
via a control orifice with the control pressure chamber and a drain
passage through which the other end of the oil hole is able to communicate
with the second drain port. A second orifice or a slit, whose cross
sectional opening area is smaller than that of the control orifice,
is formed in the supply passage at a periphery of the seat member
that comes in contact with the spool so that a flow amount of the
oil supplied to and ejected from the control pressure chamber through
the supply and drain passages after the spool contacts the seat
member is smaller than that before the spool contacts the seat member.
A solenoid valve valve part for controlling a fuel injector in
a fuel injection system has a valve needle, the open and closed
positions of which may be controlled by the solenoid valve valve
part. The solenoid valve valve part has a valve ball which rests
on a valve seat and which lifts up from the valve seat when current
flows through the solenoid valve valve part. The valve seat is in
hydraulic connection with the fuel injector via a borehole. When
the valve ball lifts up from the valve seat, a pressure medium such
as high-pressure fuel flows through the borehole into a pressure
relief chamber in the solenoid valve valve part. In the further
progression this causes the fuel injector to open. To prevent the
formation of cavitation bubbles and the damage thus caused, the
borehole includes, at least in part, one or more sections having
a cross section which continuously expands in the direction of the
valve seat. A separation in flow brought about by sharp transition
edges, which may cause cavitation bubbles, is thus counteracted.
A solenoid valve comprises a diaphragm type valve member installed
in a casing. The valve member is movable between an open position
wherein the valve member is separated from a valve seat thereby
to open the same and a close position wherein the valve member is
seated on the valve seat thereby to close the same. The valve member
has thereon a magnetic material. A biasing member is provided for
biasing the valve member in a direction to cause the valve member
to assume the close position. An electromagnetic actuator is installed
in the casing. The actuator has a work part that faces the valve
member. The work part produces a magnetic force to attract the valve
member causing the same to assume the open position against a biasing
force of the biasing member when the actuator is energized and producing
no magnetic force to leave the valve member causing the same to
assume the close position due to the biasing force of the biasing
member when the actuator is deenergized.
An expansion valve 1 integrated with a solenoid valve includes
a valve body 10 and a valve chamber 20 formed inside the valve body
10 to which a high-pressure refrigerant is introduced. A valve member
30 forms a throttle flow path between a valve seat 40, and controls
the amount of refrigerant flowing therethrough. The valve body 30
is operated by the movement of a stopper member 80 of a power element
60 via an actuating rod 100. The high-pressure refrigerant acts
on a surface 80a of the stopper member 80 opposite to a diaphragm
70 via a pressure equalizing passage 12, a connecting chamber 22
of a solenoid valve 200, and a pressure equalizing passage 14. The
stopper member 80 is sealed between the guide member 90, so that
the high-pressure refrigerant does not act directly on the diaphragm.
A normally open solenoid valve, includes: a coil; a fixed core
that is excited when the coil is energized, the fixed core having
a through hole and an opening formed at an end of the throughhole;
a valve seat disposed at the opening; a valve element inserted through
the through hole, the valve element including a valve part for coming
into contact with the valve seat and a roughly columnar shaft part
extending from the valve part; and a movable core that pushes and
moves the valve element. The shaft part has a plurality of sliding
portions that are slidable on the inner surface of the through hole
and are formed to be spaced in an axial direction of the shaft part
and a narrowed portion having an outer diameter smaller than the
sliding portions between the plurality of sliding portions.
In a twin-solenoid valve D comprising two valve members V which
are located side by side and are actuated in closing direction by
a common solenoid M via a T-shaped force transmitting member, a
stem 4 of which is guided in a slide guidance 3, a radial safety
clearance X is provided between the slide guidance 3 and the stem
4, and a tilt joint K is formed between the stem 4 and an armature
B or a movably guided armature ram 2 of the solenoid M.
A coupling solenoid valve, of which both side faces in the valve-width
direction are coupling faces for coupling another solenoid valve,
including a main valve unit for switching a fluid channel using
a spool, and a solenoid operating unit for driving the spool, wherein
a housing of the main valve unit is divided into plurality of blocks,
a valve hole for accommodating the spool is formed in a center block,
a bottom block is made up of a synthetic resin, plurality of coupling
communication holes are formed in this bottom block, and also a
connection tube is formed in an integrated manner.
In a solenoid valve 10, an annular oil groove 66 is formed at a
portion corresponding to a spring chamber 56 on the external surface
of a sleeve 19, a drain passage 68 is formed to make an upper part
of the annular oil groove 66 communicate with the outside of an
insertion bore 61, and a throttle hole 67 is provided at a lower
part of the annular oil groove 66 for making the annular oil groove
66 communicate with the spring chamber 56. Since the annular oil
groove 66 communicates with the outside of the insertion bore 61
at its upper part through the drain passage 68, it can be realized
to store the operating oil to the height of the upper part of the
annular oil groove 66, so that the operating oil can be reserved
in the spring chamber 56 which communicates with the annular oil
groove through the throttle hole 67. Further, the operating oil
is supplied from a feedback port 48 next to the spring chamber 56
through a clearance between the spool valve 19 and a valve hole
18. Thus, the solenoid valve 10 is able to secure the damping effect
of the working oil on the spool valve 19 and a plunger 17 and to
suppress the self oscillation even while being operated in the atmosphere
for a long time.
To obtain a manifold type solenoid valve assembly in which an solenoid
valve which is equipped with an output port and an solenoid valve
which is equipped with no output port are mixed and mounted on a
common manifold base. On a valve mounting part of the manifold base
which has a plurality of the valve mounting parts of the same type,
a first solenoid valve which is equipped with an output port for
external piping connection is mounted and a second solenoid valve
which is equipped with no output port is indirectly mounted through
an intermediate block which is indirectly equipped with an output
port for the second solenoid valve.
According to the present invention, there is provided a diagnosis
method for a solenoid valve which includes: energizing and deenergizing
cyclically a solenoid of the solenoid valve to repeatedly fully
open and fully close the solenoid valve; when the energizing and
deenergizing causes collisions of a moving member of the solenoid
valve against at least one of a first and a second seat formed in
a housing of the solenoid valve and noises are thus generated by
the collisions, detecting occurrence intervals of the noises; and
diagnosing whether the solenoid valve is in normal or abnormal condition
based on the detected occurrence intervals of the noises.
A solenoid valve includes a valve body defining a chamber that
receives a plunger actuated by an armature, having flow path forming
holes which are radially defined to serve as flow paths of a brake
hydraulic line extending between a master cylinder and a brake mechanism,
and fitted into a pump housing, a plunger seat accommodated in the
valve body and applied with hydraulic pressure supplied from the
master cylinder, a main check valve that opens and closes the flow
paths through detachment and attachment between the contact end
of the plunger and the plunger seat to switch flow of hydraulic
pressure from the plunger seat through the valve body to the brake
mechanism, and a return check valve to return oil in an axial direction,
which is parallel to the plunger seat axially accommodated in the
chamber and perpendicular to the flow path forming holes.
A dual wheel foldable hand truck with a nose plate has a skeletal
frame including laterally spaced vertical side rails. The frame
has hingedly connected upper and lower frame sections with upper
and lower side rails meeting at side rail interfaces. Handle operated
lock slides are carried by the upper rail sections for downward
sliding movement to releasably lock the frame sections in planar
alignment. The foldable nose automatically locks in operative position
when swung down from stowed position.
A hand truck having load shifting member which tilts the hand
truck under conditions of greater leverage than that available by
grasping the frame of the hand truck is disclosed. The load shifting
member comprises a spring retracting lever rotatably attached to
an axle journaled from the frame of the hand truck such that when
in a retracted position, the lever is substantially parallel to
the frame. Pulling on the upper end of the lever rotates the lever
such that the lower end of the lever engages the lower portion of
the hand truck frame, shifting the center of gravity of the loaded
hand truck such that it may be more easily tilted to a position
for moving the hand truck. A spring returns the lever to a retracted
position when not in use.
A hand truck comprises a movable platform configured to lower a
weight of a full beer keg to the ground from a height of a truck
loading surface. The hand truck comprises a lowering mechanism comprising
a controlled resistance device configured to lower the platform
at a controlled rate. In one embodiment, the controlled resistance
device comprises a plurality of springs and a pneumatic cylinder.
A hand truck provided with an ejector mechanism which includes
a pusher carried by the truck frame and, when actuated, moves forwardly
across the truck platform to sweep a load off of the platform. The
pusher plate is actuated by a foot actuated pedal or bar. Linkage
between the pedal and plate results in response to vertical movement
of the pedal. The ejector mechanism may be added into a number of
hand trucks already in the field, or may be incorporated in newly
produced trucks.
