A clutch regulator for vehicle comprises a main body provided with an oil passage inside thereof; an opening and closing member provided inside of the main body in a slide manner to open and close the oil passage; an elastic member configured to elastically press the opening and closing member toward the oil passage side; and a plug member installed in the main body to support the elastic member.

A hydraulic fluid expansion tank is located inside a housing of a drive device and includes an upper check valve and a lower check valve in communication with a sump located within the drive device and an internal volume of the expansion tank. The tank may also include a vent opening in communication with a vent of the drive device that is in communication with atmospheric pressure.

A pressure equalization element for a housing, such as a lithium-ion accumulator, includes a membrane and at least two parallel non-return valves. The membrane is connected in series to the non-return valves, which are positioned opposite each other. The non-return valves are formed by two valve plates and a valve membrane. The plates define at least one outlet chamber and at least one inlet chamber which each have a respective entry opening and exit opening. The membrane is positioned between the plates and includes at least two valve dampers, the entry openings of the inlet and outlet chambers sealed by a respective damper. Pressure equalization elements of this type can thus be cost-effectively and logically implemented via few components, while avoiding loose components. Such elements can be included in, for example, a housing, battery cell module, or motor vehicle.

A fluid valve has a valve plug configured as follows. In order to control a flow rate of a fluid between a first pressure chamber and a second pressure chamber, the valve plug is provided so as to be openable and closable in accordance with a difference between forces generated by pressures in the pressure chambers and resilience of an elastic member. The fluid valve includes an opening motion promoting portion. The opening motion promoting portion promotes an increase in degree of opening of the valve plug after the valve plug has been opened.

The present disclosure relates to a bidirectional valve design that provides for more rapid deflations/evacuation of fluid flow and in one example includes a valve body, a spindle piston movably coupled in a bore of the valve body and an electronically controllable motor that moves the spindle valve between a fluid evacuation position and a fluid fill position. In one example, the spindle piston includes piston structures on ends of a threaded rod. In another example, a mattress system is disclosed that employs the valve and a fluid source to provide quick evacuation of air from a patient support. In another example, the valve is coupled to an alternating pressure block valve which is then coupled to a patient support.

A pressure relief valve to balance the pressure between a cargo tank and the ambient atmosphere is described. The valve is so arranged that the velocity of the out flowing gas jet at no time is under a preset value when the valve is in open position. The valve comprises a valve body (2) designed to act against a valve seat (1) located in a structural outlet (5a) from the cargo tank, which valve body (2) is connected to a rod (7) extending into the structural outlet (5a) opening (5). The rod (7) is being supported and guided by a frame structure (6) extending into the structural outlet (5a) opening (5) and fixed to the structural outlet (5a).

One embodiment relates to a valve device. The valve device includes: a valve case; a valve element slidably disposed within a valve chamber defined in the valve case; and a positive pressure spring configured to urge the valve element toward a valve seat in the valve case. The valve element includes an outer circumferential portion having a predetermined length extending along an inner circumference of the valve chamber. The outer circumferential portion includes plural opening portions. And, ribs project from the inner circumference of the valve chamber to enter into the opening portions, thereby limiting movement of the positive pressure spring in a radial direction.

A clutch regulator for vehicle comprises a main body provided with an oil passage inside thereof; an opening and closing member provided inside of the main body in a slide manner to open and close the oil passage; an elastic member configured to elastically press the opening and closing member toward the oil passage side; and a plug member installed in the main body to support the elastic member.

A valve includes a valve disc that partitions one chamber and another chamber. The valve disc includes annular bosses and seats at each of the one chamber side and the other chamber side, and an auxiliary seat at the other chamber side. The boss is formed to support leaf valves. The seats are formed on outer peripheral sides of the respective bosses. At least one of the seats is disposed to project with respect to the boss of the corresponding chamber side. An outer peripheral end of the seat on the one chamber side is disposed on an outer peripheral side with respect to an outer peripheral end of the seat on the other chamber side. The auxiliary seat is formed on an outer peripheral side of the seat, and have a height equal to or greater than that of the seat on the other chamber side.

A tank holding a quantity of liquid releasably connects to an electric pump module through a connector to provide a portable sprayer. The tank connects to a feed line that supplies spray nozzle with the liquid. The connector combines a quick disconnect connector with a pressure relief valve. The electric pump module includes an electric pump, a switch assembly, and a check valve. The electric pump module directs gas through the check valve into the connector to increase the gas pressure in the tank and force the liquid in the tank to flow through the feed line and out the spray nozzle. The switch assembly turns off the electric pump when the gas pressure in the tank exceeds a predetermined limit while maintaining the flow of liquid through the spray nozzle.
