Abstract:
A compressed air processing system for motor vehicles, comprising:an electromechanical pressure regulator and a multicircuit safety valve having at least one load circuit connected thereto, each load circuit being separately lockable by an assigned pressure control unit of a plurality of pressure control units, said pressure regulator and said multicircuit safety valve being disposed in a housing, and a pressure limiter arranged between at least one of the pressure control units and a pressure regulator output, wherein, in a zero-current condition, the pressure limiter limits a supply hole for at least one of the pressure control units to a defined output pressure, wherein the housing also comprises a pressure regulator solenoid valve for controlling the pressure regulator, wherein the housing also comprises a regeneration solenoid valve by which the pressure regulator is controlled, and wherein the pressure limiter has a two-circuit construction and is held in an open position by the regeneration solenoid valve and then by the pressure regulator solenoid valve.
