The present invention concerns a tapping device for a keg tap with a holding element (17) for a socket (1) having a keg connection and therein beer pipe (2) sealed off against a pressure chamber with tap valve and tapping element (9) in which, according to the invention, the socket (1) has a spiral-shaped slot (3) with a pitch corresponding at least to the opening path of the valve opening element (9), into the socket (1), a bayonet collar can be introduced from above which has its own slot (3′) which can be brought into congruence with the slot, as well as an opposite-lying guiding edge (26) of the same pitch, whereby a downwardly open entrance is associated with the guiding edge (26). Between the bayonet collar (4) and the socket (1) is movable held an inwardly hollow tapping plunger (6) with a valve opening element (9) and connected with a circumferential lifting lever (7) passing through the slot (3, 3′), lying opposite which is arranged a counter spigot (8) guided on the guiding edge (26). Into the tapping plunger (6) is pushed an immersion plunger (13), provided with O-ring (10, 11, 12), which inwardly has a pressure chamber (14) sealed off against the tapping plunger (6) and a connecting bore (15) to this. The immersion plunger (13) carries on the inside the beer pipe (2) provided with a bottom seal (16), whereby, between immersion plunger (13) and beer pipe (2), a free space is left free as pressure chamber (37). The socket (1) possesses, connecting on to the holding element (17), a collar (18) against which is sealed the tapping plunger (6) with an upper O-ring (19), whereby a transverse bore (20) runs in the tapping plunger below the O-ring.

A tapping device for keg taps comprising: a socket with an upper and a lower end, the socket having a holding element for connection to a keg valve and a first spiral shaped slot; a bayonet collar within the socket, the bayonet collar having a second spiral shaped slot which is congruent with the first slot and having a pitch that is the same as a pitch of the first slot, the bayonet collar also having a guiding edge of the same pitch as the second slot and lying opposite to the second slot, the guiding edge having an entrance open towards the lower end of the socket; an inwardly hollow tapping plunger movably held inside the socket and the bayonet collar, the tapping plunger having a valve opening element; a circumferential lifting lever connected to the tapping plunger and passing through the first slot and the second slot; a counter spigot connected to a side of the tapping plunger that is opposite a connection of the lifting lever to the tapping plunger, the counter spigot being guided on the guiding edge; an immersion plunger within the tapping plunger, the immersion plunger having three spaced O-rings and between two of the three O-rings is a connecting bore; a beer pipe contained within the immersion plunger, the beer pipe having a bottom seal, and between the bottom seal, the immersion plunger and the beer pipe is an annular free space that constitutes a first pressure chamber; and a collar in the lower end of the socket, connected to the holding element, with the tapping plunger sealed off against the collar by a two additional O-rings to form a second pressure chamber, and between the two additional O-rings runs a transverse bore in the tapping plunger.
