Abstract: A controller valve with a valve body and a valve cartridge. The valve body has a water inlet, a primary water outlet, and a bypass water outlet. The valve cartridge is positioned within the valve body and has a diaphragm that fluidly isolates an upper chamber from a lower chamber within the valve cartridge. A piston is attached to the diaphragm and is configured to move within the valve cartridge between an upper position and a lower position. When the piston is in the upper position, the valve cartridge limits water flow through the primary water outlet and allows water flow through the bypass water outlet, and when the piston is in the lower position, the valve cartridge allows water flow through the primary water outlet and limits water flow through the bypass water outlet.

Abstract: A pressure relief valve includes a valve body; a valve cover matched with the valve body; a flexible element positioned between the valve body and the valve cover and having a through hole; and a breathable film covering the through hole. The flexible element has a compression portion at least partially surrounding the through hole and configured to be deformable to make the flexible element displace relative to the valve body. A battery pack can use the pressure relief valve. Due to the use of the pressure relief valve, internal pressure of the battery pack can be controlled.

Abstract: A valve includes a housing. A stroking valve is operatively connected to the housing for valve stroking movement relative to the housing in a direction of a longitudinal axis of the housing. The stroking valve has an open position for flow through the housing and a closed position for blocking flow through the housing. The stroking valve is configured to make sealing contact with a second face seal between the seal block and the stroking valve after a first portion of a stroke from the open position to the closed position prior to making sealing contact with a first face seal between the stroking valve and the housing.

Abstract: A valve device includes male and female housings having, respectively, exterior and interior annular channels. The male housing is receivable into the female housing such that the exterior and interior annular channels together define a toroidal tube. The male and female housings together define a fluid through-passage. There are first and second valve elements disposed, respectively, in the male and female housings. Ball locks are receivable into the toroidal tube. The ball locks axially lock the male and female housings together but permit rotation between the male and female housings. A lock includes first and second pin holes in, respectively, the male and female housings. The lock is engageable to rotationally lock the male and female housings when the first and second pin holes are in alignment.

Abstract: A cleaning device for a vehicle provides a liquid cleaning pulse and/or a compressed air cleaning pulse for a cleaning nozzle. The cleaning device includes a module compressed air connection for receiving compressed air and a pressure cylinder with a cylinder volume. A movable separator divides the cylinder volume into a compressed air receiving chamber and a cleaning liquid receiving chamber in a fluid tight manner. The air chamber has an air chamber connection which can be supplied with compressed air. Contraction of the liquid chamber occurs when filling the air chamber by moving the separator against a restoring force. A switching valve establishes a pneumatic connection between the module compressed air connection and the air chamber connection. A bypass valve establishes a pneumatic connection between the module compressed air connection and the compressed air nozzle line while bypassing the switching valve for providing a bypass compressed air flow.

Abstract: An oscillating diaphragm valve is provided. The valve is configured such that, when the diaphragm is in a closed position, pressure of a fluid supply opens the valve, and when the diaphragm is in an open position, the pressure of the fluid closes the valve. The valve internals are formed as a single, enclosed piece, with openings provided only for supply and consumption. The pilot-operated diaphragm-type valve uses a return spring for the diaphragm that applies a biasing force to an outside surface of the valve internals. Additionally, an actuator is provided to selectively arrest the diaphragm in an open or closed position by applying force to a different outside surface of the valve internals.
