Electropneumatic control valve with a back-up valve |
摘要 |
Electropneumatic control valve for a pneumatic brake system of a vehicle, having a divided valve housing consisting of 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. The piston can be acted upon by way of a pilot valve arrangement accommodated in the pilot valve housing in order to switch the compressed-air flow between at least one brake line connection arranged on the relay valve housing, a supply pressure connection and as a bleeder connection by way of an interior valve seat arrangement. A control connection of a back-up valve of the pilot valve arrangement is also arranged on the relay valve housing, and by way of a valve-internal pressure medium duct is connected with the back-up magnetic valve accommodated in the pilot valve housing. Internal pressure medium ducts are arranged and sealed in a manner that allows the pilot valve housing to be produced without machining.
