Title: Failsafe valve for trailer air brakes - has interlock to isolate intact circuit and valve element moving with normal braking to prevent sticking
Inventor: SKACH KUNO DIPL ING
IPC: B60T17/18
Filed: 1975-11-13
Abstract: The dual circuit air brakes are protected by pressure control valves which isolate the intact circuits if the other circuit fails, especially a trailer connection. The protective valve element is integrated into the brake control circuit in such a way that it moves with normal braking to prevent sticking through long periods. The valve element is designed to operate over its full stroke every time the brakes are applied, with momentary venting and blocking, which does not affect the braking effort of the system. The failsafe interlock is thus fully operative at all times.
