ABSTRACT:
The discharge valve for a flushing cistern (1) has a main valve (V) with a main valve body (3) which forms a piston above which a relief chamber (4) is arranged. By means of a first auxiliary valve (HV1), the relief chamber (4) can be emptied, at least in part, in order to trigger flushing. By means of a second auxiliary valve (HV2), the relief chamber (4) can be flooded in order to interrupt flushing. The first auxiliary valve (HV1) and the second auxiliary valve (HV2) have a common auxiliary valve body (7) which, when flushing is triggered, releases the valve opening (68) of the first auxiliary valve (HV1) and closes the valve opening (6) of the second auxiliary valve (HV2). A valve seat (18) of the first auxiliary valve (HV1) and a valve seat (21) of the second auxiliary valve (HV2) are preferably arranged on the main valve body. The discharge valve can be actuated with a comparatively small actuating force and small actuating distance and allows a very compact construction with a comparatively small number of components.
