A fast valve actuation system for an automatic vehicle transmission includes a pair of spring-biased shift valves. Solenoids control the application of pressurized hydraulic fluid to the head of each of the shift valves. Each shift valve has at least one port that is coupled to a fluid chamber of a torque transferring mechanism of an automatic transmission. The position of each of the shift valves determines whether its ports are connected with fluid pressure. Fluid passages connect the head of each shift valve to the spring pocket of the other shift valve.

A faucet-mounted filter system includes a body forming a fluid chamber having a water inlet, a quick connect device positioned adjacent the water inlet for mounting the filter system to a water faucet, a filtered water flow path disposed within the body and in fluid communication with the water inlet, an unfiltered water flow path disposed within the body and in fluid communication with the water inlet, a diverter valve disposed within the fluid chamber and operable to open and close the filtered and unfiltered water flow paths, a seal, an actuator engaging the diverter valve to open and close the filtered and unfiltered water flow paths, a flow meter connected to the body and in fluid communication with the filter flow path, a filter housing connected to the body and having a reservoir, and a filter cartridge disposed within the reservoir.

A pilot valve system is controlled by the pressure differential between a lower chamber and an upper chamber. A fluid passageway in the lower chamber fluidly connects an inlet to first and second outlets. By varying the pressure differential, the placement of a stem within the fluid passageway is varied so fluid can flow between the inlet and only one of the first and second outlets at a time. Pressure in the lower chamber can be varied by using a second fluid to exert pressure against a bottom end of the stem. Pressure in the upper chamber is varied by using an adjusting screw to urge a spring against the diaphragm.

A valve element movement mechanism includes: a first valve stem having one end portion to which a first valve element to close and open an area between one of the large diameter portion and the small diameter portion is fixed; a second valve stem having one end portion to which a second valve element to close and open an area between the other of the large diameter portions and the small diameter portion is fixed; a first bellows having one end portion fixed to a first bellows flange and the other end portion fixed to the first valve element; a second bellows having one end portion fixed to a second bellows flange and the other end portion fixed to the second valve element; a frame disposed outside the main passage; and an actuator to move the frame in the directions in which valve elements are closed and opened.

A rocket engine is provided with a propellant valve controlling the output of a propellant tank. The valve is configured to induce a vortex in the propellant as it passes the propellant valve. Plural rocket engines may be supplied by a single valve, the valve inducing a vortex in the propellant which is then supplied to plural propellant lines configured to enhance the vortex induced by the valve.

A faucet-mounted filter system includes a body forming a fluid chamber having a water inlet, a quick connect device positioned adjacent the water inlet for mounting the filter system to a water faucet, a filtered water flow path disposed within the body and in fluid communication with the water inlet, an unfiltered water flow path disposed within the body and in fluid communication with the water inlet, a diverter valve disposed within the fluid chamber and operable to open and close the filtered and unfiltered water flow paths, a seal, an actuator engaging the diverter valve to open and close the filtered and unfiltered water flow paths, a flow meter connected to the body and in fluid communication with the filter flow path, a filter housing connected to the body and having a reservoir, and a filter cartridge disposed within the reservoir.

A multi-way valve has an upper part, a lower part and a central part connected to the upper part via an interposing first membrane and the lower part via an interposing second membrane, wherein the upper and lower parts contain recesses on the upper and lower part faces facing the membranes, where a control fluid is introducible into the recesses, the central part contains a pair of openings in regions opposite the recesses on the central part faces lying adjacent to the membranes, where while introducing the control fluid into a recess, the membrane closes respective opposite openings in the central part, and where the membrane otherwise recedes into the recess, thereby releasing the opposite openings, where valve connections are mounted on the upper or lower part such that the central part can have a very thin design while preventing dead regions in the channel systems.
