Abstract
A valved keg closure unit is secured in a keg bushing by means of an axially shallow, externally threaded annular collar, received in an internally threaded upper portion of the bushing and overlying an upper cylindrical element of the closure unit that comprises a coaxial annular valve seat. The collar bottoms on an upwardly facing circumferential shoulder in the bushing to prevent excessive axial compression of a resilient sealing ring between the cylindrical element and the bushing. To prevent rotation of the cylindrical element, it has circumferentially spaced, radially outwardly projecting tits, received in axially extending internal grooves in the bushing. A downwardly projecting annular wall portion of the cylindrical element, having a circumferential internal groove, surrounds the top portion of a fixed tubular element, which has a radially outwardly rolled circumferential land received in said groove to permanently connect those elements. An axially movable siphon tube, having an annular valve element at its top that is engageable with said valve seat, is restrained against skewing by integral inwardly struck fingers on the tubular element.
