摘要： In a variable-delivery vane-type rotary compressor, a rotational displacement of an adjust member relative to a front member fixedly closing a front end of a cam ring varies a compression starting point of a rotary vane in a working chamber formed in the cam ring. The rotational displacement of the adjust member is controlled by an adjust member actuating unit in response to a pilot pressure applied to the adjust member actuating unit from a pilot pressure applying unit. The pilot pressure applying unit includes a first passage communicating the adjust member actuating unit with a valve unit, a second passage communicating an induction chamber with the valve unit, and a third passage communicating a discharge chamber with the valve unit. The valve unit, when it is most displaced in a first direction, fully blocks the communication between the adjust member actuating unit and the induction chamber through the first and second passages while allowing the communication between the adjust member actuating unit and the discharge chamber through the first and third passages for applying a pressure within the discharge chamber to the adjust member actuating unit as the pilot pressure. On the other hand, the valve unit, when it is most displaced in a second direction opposite to the first direction, fully opens the communication between the adjust member actuating unit and the induction chamber through the first and second passages for applying a pressure within the induction chamber to the adjust member actuating unit as the pilot pressure.

摘要： A power steering system includes a fluid pump, a steering gear, a high-pressure passage connecting the fluid pump to the steering gear, and a flow control valve having a first chamber forming a part of the high-pressure passage. A metering orifice is disposed in the high-pressure passage between the first chamber and the steering gear. A feedback passage distributes feedback pressure developed in the high-pressure passage downstream of the metering orifice to a second chamber of the flow control valve. An exhaust port communicates with the first chamber. A movable valve spool is disposed in a valve bore and has one end exposed to the first chamber and opposite end exposed to the second chamber. A valve spring is disposed in the second chamber together with a slide coupled with an external actuator. One end of the valve spring is seated on the opposite end of the valve spool and opposite end thereof is seated on the slide. The actuator is responsive to a control signal to position the slide thereby varying force with which the valve spring urges the valve spool. A control unit develops the control signal in response to turning maneuvers.

摘要： A power assisted steering apparatus for a vehicle has a driving source and an actuator for the vehicle's steering mechanism, to power assist the steering operation. The driving source, such as an engine, continuously drives a pump. A working passage is arranged so that working oil discharged from the pump is introduced into the actuator. A check valve is disposed in the working passage, between the actuator and the pump so that the working oil flows only one way to the actuator. An accumulator is connected to the working passage, between the check valve and the actuator to maintain a predetermined pressure in the working passage. A regulator is connected to the working passage, between the pump and the check valve to regulate flow to the actuator. When the pressure within the working passage reaches the predetermined pressure, the working fluid is dumped to a reservoir, bypassing the check valve, the accumulator, and the actuator.
