ABSTRACT:
In a brake valve for the operation of the service brake and spring-loaded brake installation of a utility vehicle trailer, a service brake valve (3) and a spring-loaded valve (1) are provided in a common housing (5) in mirror image arrangement. The two valves, operating in a manner known per se, are constructed of identical components and a common ventilation in the form of a ventilation insert (47) in the center of the housing (5). The two valves are fed either from a common reservoir (55) or from separate reservoirs (77, 79) provided for each of the valves, which reservoirs can be refilled through overflow valves (81, 83) without reflux from the line of the trailer holding reserve air.
