| 摘要 |
The invention relates to an electropneumatic control valve for a compressed air braking system on a vehicle, comprising a valve housing (1) with a lower relay valve housing (2) and an upper pilot valve housing (3), enclosing a control chamber (5) in which an axially displaceable control piston (6) runs. The above may be pressurised by a pilot valve arrangement (7), housed in the pilot valve housing (3), in order to switch the compressed air flow between at least one brake line connector (12), arranged on the relay valve housing (2), a feed pressure connector (18) and a bleed connector (14) by means of an internal valve seat arrangement (11). The control connector (23) for a backup valve (17) to the pilot valve arrangement (7) is arranged on the side of the relay valve housing (2) and connected to the backup solenoid valve (17), mounted on the side of the pilot valve housing (3), by means of an internal pressure channel (24) within the valve, in order to produce a pilot valve housing (3) which may be produced without machining.
