<p>A faucet (1) serves for tapping of a liquid, e.g. beer which on the dispense spot is in a container under pressure of CO2. The faucet comprises a tubular valve casing (2) defining, when in normal position of use, a vertically extending axis. This casing (2) has at the side a tubular liquid inlet (23) and below this a spout (3). In the casing there is furthermore mounted a vertically movable valve (5) which by means of for example a handle can be raised both to an upper position, where the faucet is open, and lowered to a lower position, where the valve abuts a valve seat (31) in the casing and closes the faucet. This valve seat extends down to the underside of the spout (25), and since the end part of the valve (39) has a complementary shape in relation to the valve seat, the faucet will close tightly right directly at the opening of the spout, and the air will be prevented from penetrating into the interior of the faucet and thereby start a putrefactive process in the beer residues which might remain here after tapping.</p> |
