Abstract:
1. Electropneumatic control valve for a pneumatic brake system of a vehicle, having a divided valve housing which includes a lower relay valve housing and an upper pilot valve housing which enclose a control chamber in which an axially adjustable control piston is guided which can be acted upon by way of a pilot valve arrangement accommodated in the pilot valve housing in order to switch compressed-air flow between at least one brake line connection arranged on the relay valve housing, a supply pressure connection and a bleeder connection by way of an interior valve seat arrangement, wherein a control connection of a back-up valve of the pilot valve arrangement is arranged on an outer surface of the relay valve housing, and by way of a valve-internal pressure medium duct is connected with the back-up valve accommodated in the pilot valve housing, in a manner which permits the pilot valve housing to be produced without machining.
