Multi-circuit safety valve for compressed air supply system of vehicle, has check valve, which is arranged parallel to overflow valve securing service brake circuit, where another check valve is arranged in pneumatic connection line

摘要

The multi-circuit safety valve (94) has a check valve (18), which is arranged parallel to an overflow valve (14,16) securing the service brake circuit (10,12). Another check valve (26) is arranged in a pneumatic connection line (20). The pneumatic connection line is connected to a joint connection (28) downstream by a third check valve (30) securing the parking brake circuit (22) against the trailer supply circuit (22'). An independent claim is included for a method for operating a multi-circuit safety valve for a compressed air supply system of a vehicle.
