換弁５を介在させて成るポンプ流量制御装置。In a device in which the flow rate control device 2 of the variable displacement hydraulic pump 1 is controlled by an external pilot pressure acting through a pilot circuit 3, an external pilot is normally connected to the flow rate control device 2 in the pilot circuit 3. A pump flow rate control device interposed with a switching valve 5 which removes the pressure acting on the flow rate control device 2 due to the discharge pressure to a tank 4 when the discharge pressure of the pump 1 on which the pressure is applied is exceeded.
