ABSTRACT:
A hydraulic circuit for an actively controlled suspension system employs first and second pressure relief valves disposed in a hydraulic pressure source circuit for relieving excessive pressure. The second pressure relief valve is provided a lower relief pressure than that of the first pressure relief valve. Means for selectively connecting and disconnecting the second pressure relief valve is disposed in the hydraulic pressure source circuit at an orientation upstream of the second pressure relief valve. The means is positioned at shut-off position to disconnect the second pressure relief valve when a vehicle traveling speed is higher than a predetermined speed. The means is responsive to the vehicle speed lower than the predetermined speed for establishing connection between a pressurized fluid source to the second relief valve for relieving the pressure at lower level than that established when the vehicle speed is higher than the predetermined speed.
