グ装置。 In a steering system where a single pump can operate the steering unit and drive other actuators, a pilot is used to control the flow rate control valve, which is necessary to distribute the pump flow preferentially to the steering unit during steering operation. A power steering device characterized in that a one-way throttle valve is provided in the line to slow down the movement speed only when the main spool of the flow control valve moves in the direction of distributing the pump flow rate to the actuator side.
