ABSTRACT:
A portable key tapping unit for a keg having a conventional valve assembly comprises concentric inner and outer body members, the latter cooperable with lugs on the keg to provide a bayonet connection. A small diameter lower portion of the inner body member is surrounded by the outer body member and has a cam connection therewith. A concentric larger diameter upper portion of the inner body member comprises a cylindrical upwardly opening pump chamber wherein an upwardly biased plunger is reciprocable vertically. A liquid passage in the inner body member has a concentric inlet at the bottom thereof and opens laterally to one side of it. A vertical gas passage through the inner body member, spaced from its axis, opens downwardly to its bottom and upwardly to the pump chamber. An elastic ring confined between the body members provides a gas seal between them and also serves to transmit limited torque from the inner to the outer body member so that a rotational movement in one direction of the inner body member establishes the bayonet connection with the keg and thereafter effects downward movement of the inner body member to its position in which it holds open the valves of the keg assembly.
