Abstract:
Disclosed is a device for controlling the pressure of a fluid supplied to a power steering apparatus in response to the speed of a vehicle. The device is arranged such that in a fluid return passage from the power steering apparatus to a pump, there is provided a throttle valve controlled by the speed of the vehicle, so that the controlled oil pressure is guided to an oil pressure reaction chamber in the power steering apparatus.
