Abstract

Overload protection relay valve (12) for combined service and spring-loaded brakes of vehicles, in particular road vehicles, comprising a pressure storage chamber (36), a brake chamber (33), and a first control chamber (27) and a second control chamber (30), it being possible for compressed air to be admitted to the pressure storage chamber (36) from a storage reservoir (6), for the pressure for releasing the spring-loaded brake to be admitted to the brake chamber 33), for the braking pressure of the service brake to be admitted to one control chamber (30) and for the control pressure of the spring- loaded brake to be admitted to the other control (27), and a relay piston (22, 22', 22''), which is driven by the pressure in one of the control chambers and which actuates a double valve body (34), by which the brake chamber (33) can be connected either to the pressure storage chamber (36) or to the atmosphere, wherein, in addition to its partial working area (26) associated with one control chamber (27), the relay piston (22, 22' and 22'') comprises on the same side a second partial working area (29) which is associated with the other control chamber (30).
