Pneumatic brake system for rail vehicle

摘要

The compressed air pipe arrangement involves a connecting pipe between the control valve (8) and the spring reservoir parking brake. The connecting pipe contains a double check valve (12) whose further connection is joined via an additional pipe with the blocking valve (13) to the main air pipe (HL). In the disengaged state of the vehicle the blocking valve is switched to through flow passage. In the engaged state of the vehicle, the blocking valve is vented and blocked between the main pipe and the double check valve.
