ABSTRACT:
In order to make possible, with a valve having a sleeve (110) provided with a valve seat (112) and with a valve activating tube (118) which supports a spring-biased valve body (114) which can be tipped away from the valve seat (112), a high water flow rate even under low water pressure, it is proposed, instead of a support of the valve body (114) on the valve seat (112) during valve opening, which inhibits water flow and causes wear, as is the case with a valve which closes with water pressure, to provide the sleeve (110) in a valve which closes against the water pressure with an axial, annular shoulder (133), the diameter of which is larger than the diameter of the valve seat (112) and on which the frontal surface (162) of the tube (118) nearest the annular shoulder (133) is supported.
