control unit for a mittelpufferkupplung for rail vehicles with indirectly acting compressed air brake

摘要

In order to ensure reliable, operationally appropriate functioning of a venting valve for the main air line (8) which is also coupled by means of air coupling in mechanical central buffer couplings for rail vehicles, a control device is disclosed for the venting valves (15), which control device has in the coupled state of the central buffer coupling (1.1) and counter coupling (1.2) at least two pneumatic AND valves (16, 17) and which supplies status reports, as input signals, both from the central buffer coupling (1.1) and from the counter coupling (1.2) in order to control the venting valves (15) assigned to the couplings.
