Claim 1
Independent Claim
435 words
In a keg tapper for use with a keg having a neck with a closure valve carried therein, said neck having a flange with a tapered edge, said closure valve including a tube carrier fixed in said neck and having a first valve seat, a tube slidingly carried in said tube carrier, a first annular seal at the end of said tube, a first valve member positioned within said tube, a first spring for urging said first valve member against said first annular seal, and a second spring for urging said first annular seal against said first valve seat, said tapper including in combination: a body having an axial bore and a plate for resting on said neck with at least three bosses for engaging said neck flange tapered edge at spaced locations; a plunger slidingly disposed in said axial bore of said body with said plunger engaging said first valve member of said keg closure valve; lever means carried on said tapper body for moving one of said bosses toward and away from said neck whereby movement of said one boss toward said neck moves said body and plunger toward said first valve member of the keg closure valve; said plunger including a second valve member with an axial passage and at least one radial passage through said second valve member, with said radial passage providing a flow path between the interior of said tube and said axial passage of said plunger when said second valve member is moved into sealing engagement with said first annular seal and said plunger moves said first valve member away from said first annular seal; means for moving said plunger axially in said body to bring said plunger into engagement with said first annular seal and move said tube away from said neck and move said first annular seal away from said first valve seat to provide a flow path between said valve body axial bore and the interior of said keg; and a relief valve carried in said body, said relief valve including: sleeve means defining a flow path from said body bore to the atmosphere and having a restricted passage; a plunger slidingly mounted in said sleeve means; a passage seal carried by said plunger and positioned in said restricted passage in sealing relation; a third spring positioned on one side of said passage seal and urging said passage seal away from said body; and a fourth spring positioned on the other side of said passage seal and urging said passage seal toward said body; with said plunger exposed for manual actuation of said passage seal.
