Suspension system for motor vehicle, has conveying aggregate provided with engine pump unit, whose delivery flow is arbitrarily adjustable for variation of amount of liquid within hydraulic cylinder using current less open and closed valves

摘要

The system has a conveying aggregate provided with an engine pump unit (5), whose delivery flow is arbitrarily adjustable for variation of amount of liquid within a hydraulic cylinder (6) using current less open valves (1, 3) and current less closed valves (2, 4) e.g. 2/ 2-way seat valve. The conveying direction of the engine pump unit is changed based on operating sequence of the valves. The valves are arranged in a bridge circuit on a suction side of a pump and at a pressure side of the pump. The seat valve is electromagnetically switchable into its closed or opened reversal position.
