Abstract

The valve includes an elastomer membrane(17) lying on a valve face(3) and forming with it a valve chamber(23). A single sealing element(25) protruding from the inner side of the membrane and in its neutral position lies by one sealing face(26) on the edge section of the controlled opening(14) forming the valve seat. An operating element by which the sealing element is tipped away from or lifted from the valve seat is located outside the valve chamber and is indirectly or directly connected to the sealing element.
