摘要： 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.

摘要： A gas turbine engine valve assembly having an oil shut-off valve and a compensating valve fluidly connected thereto. The compensating valve, in a first position, restricts access to a pressure-reducing oil flow path leading to an oil reservoir, and in a second position, provides access to the pressure-reducing oil flow path. The pressure-reducing oil flow path is defined by fluid flow between housing apertures, a laminar hole and an orifice. The valve assembly is operable between a first configuration, wherein the oil shut-off valve is in a fluid transfer position and a piston of the compensating valve is in a closed position to direct oil toward the engine component, and a second configuration, wherein the oil shut-off valve is in the shut-off position and the piston is in a open position to direct oil toward the oil reservoir via the pressure-reducing oil flow path.

摘要： A spool valve device includes a valve body, an actuator port, a spool, a supply passage, and a regeneration flow passage formed in the spool. An inflow port of the regeneration flow passage always communicates with the actuator port, when the spool is placed at a regeneration switching position where a predetermined moving amount from a neutral position is ensured, the outflow port of the regeneration flow passage communicates with the actuator port through the supply passage, and when the spool is placed at a position other than the regeneration switching position, the communication between the outflow port and the actuator port is blocked.

摘要： A control valve for a camshaft adjuster is provided. The control valve contains a hollow cylindrical control piston, which has radially arranged piston openings on a piston head of the control piston, which piston head has a reduced diameter in comparison with the adjacent segment. Pressure medium flows along the outer cylindrical surface of the control piston, reaches into the piston openings, and causes a flow force that depends on the relative position of the control piston in the circumferential direction. For the purpose of weakening this dependence, the piston openings and sleeve openings are distributed over the circumference, wherein the angle between the axes of the piston openings differs from the angle between the axes of the sleeve openings and wherein the same angle range covered by the piston openings and sleeve openings at the same time, in dependence on the position of the control piston in relation to the control sleeve, remains approximately the same.

摘要： To provide a regulating valve of which stability of an operation is high, a regulating valve is disclosed that includes a valve box in which a first flow channel and a second flow channel are formed; a cage having a first throttle portion provided in a boundary between the first flow channel and the second flow channel; a plug head having a second throttle portion slidably inserted into an inside of the cage; and a guide ring slidably holding a plug guide holding the plug head. In a closed state of the regulating valve, a distance between a through-hole of the first throttle portion and an end portion of the plug head on the other end side is equal to a distance between a through-hole of the second throttle portion and an end portion of the cage on the opened one end side.

摘要： A valve assembly for a pressurized container includes a valve stem and a mechanical seal. The valve stem has an open top portion, a closed bottom portion, at least one primary radial opening, at least one secondary radial opening and a valve stem passageway between the open top portion and both the at least one primary radial opening and the at least one secondary radial opening. The mechanical seal comprises a longitudinal passageway that seals the at least one primary radial opening and the at least one secondary radial opening, respectively, when the valve stem is in a closed position. Longitudinal translation of the valve stem exposes the at least one primary radial opening or both the at least one primary radial opening and the at least one secondary radial opening to the pressurized container when the valve stem is in an open position.

摘要： A flow path velocity modifier allows a control member of a control valve to operate very close to a seat ring while reducing or eliminating restricted flow areas, which results in greatly reduced flow velocity fluctuations, which results in smoother flow, between the sealing element and the seat ring. As a result, sealing elements made of relatively soft materials may be used without fear of damage from high flow velocities.

摘要： An automatic transmission uses 6 shift elements applied in combinations of four to establish ten forward speed ratios and a reverse speed ratio. The automatic transmission uses a hydraulic control system to control engagement of the six elements, control engagement of a torque converter bypass clutch, control engagement of a parking pawl, and to provide fluid for a hydrodynamic torque converter and for lubrication. The parking pawl is disengaged in response to engagement of two of the six shift elements and remains disengaged in response to engagement of other shift elements. A single valve controls several different functions associated with the two-pass torque converter. Pressurized fluid is provided by a variable displacement engine driven pump and also by an electric pump. A priority valve reduces lubrication flow when other fluid demands are high as indicated by the pump displacement control circuit.
