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.

摘要： In a power steering system of this invention, a control valve is provided for supplying working fluid to a power cylinder by an amount proportional to a steering effort supplied to an input shaft and obstructing supply of working fluid to the power cylinder when a steering wheel is in a neutral position. A conversion mechanism which includes an operation rod (operating device) capable of operating the control valve is provided for converting the steering effort supplied to the input shaft to displacement of the operation rod. A directional control valve is provided which is disposed between the control valve and the power cylinder for switching supply of working fluid from one of cylinder chambers of the power cylinder to the other according to the direction of the steering effort on the input shaft while controlling discharge of working fluid from the cylinder chambers.

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.
