Abstract
The invention relates to a tap for use in discharging limited volumes of gas, especially for inflating balloons for children, having a flexible sealing element (38) mounted on a manually actuatable control lever (32) and having two sealing surfaces, each of which cooperates with a tap seat (28,30) formed on the body (12) of the tap (10). One of the seats (28) is adapted to be engaged by an inner sealing surface of the sealing element (38) and the other seat (30) surrounding the first seat (28) cooperating with a second external sealing surface provided on a flexible circumferential lip (38') of the sealing element (38). The flexible lip (38') is provided with circumferentially spaced radial slots (39) in the outer edge thereof to limit the gas flow during initial opening movement of the tap (10) in a discharge mode of operation.
