  • Patent number: 4860931
    Abstract: A keg tap described is for domestic use, and in it an axially shiftable valve-opening rod (3) with a valve-opening element (4) is guided through an essentially cylindrical housing (1) enclosing a pressure space (2) and is inserted through a piston (8) which is arranged in the lower region of the housing (1) and which limits the pressure space (2) located here. The valve-opening rod (3) is at the same time a riser pipe and has a continuous liquid passage (7) which leads outwards from the valve-opening element (4) at one end and which, at the opposite end, merges into a liquid duct (17) cut out in a stirrup (15) arranged essentially at right angles to the liquid passage (7) and equipped with a shut-off valve (19) and with a consequently closable outflow (18). The piston (8) closing off the pressure space (2) is connected via piston rods (14) to a handle (5), by means of which the piston ( 8) is actuated independently of the valve-opening rod (3).
