PURPOSE:To obtain a car speed response type hydraulic system having simple structure by constructing a variable volume means for variable volume pump interlocked with engine rotation to be controlled by pressure in pump delivery conduit having restricting flow path. CONSTITUTION:In a rotor 1j to be rotated by engine, a delivery conduit 1f of variable volume type hydraulic pump 1 contained in a cam ring 1a to be displaced through function of pistons 1b, 1k is coupled to a hydraulic exchange valve 3a for operating an actuator 3. A branch 2j to be connected to the suction conduit 1h of suction pump 5 responsive to car speed is made to the delivery conduit 1f and a flow control valve 2 is placed in said branch section. A flow path 2d is provided at the upstream of flow control valve 2 while a conduit 1g branched at the upstream of said flow path 2d is connected to a connecting hole 1c for the piston 1b. The suction conduit 1h is connected to a connecting hole 1d for the piston 1k. |
