Abstract (en)

[origin: WO2012038285A1] Pneumatic control valve for feeding compressed air in a regulated way to a brake cylinder which can be connected via a compressed air connection (C), having at least one integrated seat valve arrangement (4, 5) for ventilating or venting the brake cylinder in accordance with the pressure in a main air line which can be connected by means of a compressed air connection (L), wherein additional valve means for the controlled re-charging of a reservoir air container, which can be connected via a compressed air connection (R), during the venting time of the brake cylinder are integrated, wherein the additional valve means comprise a choke valve (10) which has a spring reset and is inserted into a valve-internal R duct (11) which starts from the compressed air connection (R), in order to ensure throttled re-charging of the reservoir air container over at least part of the venting time of the brake cylinder.
