Vehicle stabilization system has combination valve that integrates functions of direction valve and relief valve

摘要

A direction valve connects an actuator to either a pressure supply line (12) or a return pipe (22). Pressure control valves (2) and pressure sensors (7) regulate pressure supply from a pump to the actuator. A relief valve disconnects the actuator from the pressure supply line when system error occurs. The functions of the direction valve and relief valve are integrated in one combination valve (1). The pressure supply line is connected to the pump which supplies pressure to the actuator. The return pipe is connected to a pressure-free tank.
