PURPOSE:To secure such a power steering device as capable of meeting every running condition upon securing optimum steering power, by detecting a signal which specifies the running condition of a car. CONSTITUTION:A detector D controls a pump P corresponding to each of outputters 1 and 2. The outputter 2 connected to a flow control valve F adjusts a flow characteristic of the flow control valve F according to an output signal out of the detector D and determines a feed flow rate from the pump P to a power cylinder. A solenoid valve V is connected to the detector D and opens or closes itself according to the speed signal or the like detected by this detector D. In time of being below the setting speed, the solenoid valve V keeps a close position but when exceeding the setting speed, it keeps an open position. |
