Abstract: The invention relates to a pressure control device for vehicles comprising a control device, a mechanical, pneumatic and/or hydraulic element and at least one sensor and/or at least one actuator. The invention is characterized in that, in the area of the sensors and/or actuators, recesses or cavities are provided in the control device and/or in the element. The sensors and/or actuators can at least be partially accommodated in said recesses or cavities.

Abstract: A compressed-air processing system, notably for motor vehicles, includes, in a housing, an electromagnetic pressure regulator and a multicircuit safety valve having at least one load circuit connected to it. Each load circuit can be locked separately by an assigned pressure control unit. Reliable and economical operation of the system is achieved by positioning a pressure limiter between at least one of the pressure control units and the pressure regulator output and by the fact that in the zero-current state, the pressure limiter acts on a supply hole for the control unit so as to limit the output pressure to a defined value.
