Abstract

Assembly in a compressed air system of a vehicle provided with an air ride suspension, the assembly being configured to lift the vehicle body by filling at least one air spring, the solenoid valves being switchable in cooperation with an electronic control device, and the assembly including a pressure line for filling the air springs, and the pressure line including a first branch line connectable to the pressure line via a pilot-controlled solenoid valve for filling the air springs and including first supply pipes and pilot-controlled solenoid valves for each air spring as well as a second branch line for providing a control pressure which includes second supply pipes for the pilot-controlled solenoid valves, wherein the second branch line is connected to the pressure line via a check valve, the check valve providing a block position against venting or pressure drop in the second branch line.
