Abstract
A portable keg tapping unit, cooperable with a valved keg closure, has an outer body member which makes a bayonet connection with the closure and an inner body member with a lower portion that is rotatably and axially slidably received in the outer body member, an upper portion that comprises a pump chamber, and an intermediate portion above the outer body member. In the inner body member are a liquid passage that opens to its bottom and to a nipple at one side of its intermediate portion and a gas passage that extends down from the pump chamber and opens to its bottom in laterally spaced relation to the liquid passage. A vent passage, communicated with the gas passage below a check valve therein, has an outlet at another side of said intermediate portion, which outlet is normally blocked by a push button valve. A brief opening of the push button valve relieves excess keg pressure to prevent dispensing of wild beer.
