In a vehicle suspension system configured to maintain a spring in an inoperative state,
The suspension system has a pressure regulating valve configured to operate during the pressure stroke of the hydraulic cylinder during brake operation on the vehicle to control anti-nose dive action on the vehicle, and at least during the extension stroke of the hydraulic cylinder. The damping valve has a damping valve formed so as to generate a rebound damping force when the rod is inoperative, and to confine oil in the rod side oil chamber when the damping valve is not activated. 1. A suspension system for a vehicle, characterized in that the suspension system is configured so that the rebound damping force can be changed by switching the damping force on the rebound side. (2) The suspension system for a vehicle according to claim 6, which is capable of making the rebound damping force variable by controlling the pressure of the switching valve and the damping valve. (3) The suspension system for a vehicle according to claim 1, wherein the switching valve orifices controls the damping valve to make the rebound damping force variable. (4) The suspension system for a vehicle according to claim 1, wherein the switching valve is configured to be switched by an electric signal. (5) The suspension system for a vehicle according to claim 1, wherein the switching valve is configured to be switched by pilot pressure.
