The present invention relates to an apparatus (1) for tapping of water, which comprises a valve device (4) with an inlet (19), connected to a water source, as well as an outlet (21) and a seat (29), positioned there between and actuated by spring-loaded shut off and opening means (26, 35). The valve device (4) comprises according to the invention two cup-shaped halves (10; 11), facing each other, between which by means of an edge area all around a rubber elastic membrane (35) is fastened, which separates the hollow spaces (34; 37) of the two halves from each other, which membrane within one of the hollow spaces (37) abuts said seat (29), which inwardly limits the inlet opening (16) of the inlet (19), and which membrane within the other hollow space (34) is actuated by means of said shut off and opening means, designed as a valve plate (26), which presses the membrane against the seat (29), which plate is influenced by said spring actuation and extends through the corresponding body half (11) with a spindle (25), to which drawing means (5-8; 30) are connected for a temporary pressure relief of the membrane within the seat area and consequently also a discharge of the medium flow into the respective hollow space (37) and out of the outlet (21).
