Abstract: A tap head for keg fittings comprises a sliding guide means containing an annular seal and a guideway for pushing the tap head onto the protruding rim of a plate of the keg fittings, wherein at least the sliding guide means of the tap head consists of spring elastic material and a projecting guide piece of the guideway engages under the rim of the plate. The modulus of elasticity of the material forming the sliding guide means and the geometry and the dimensions of the guide piece are determined such that the guide piece undergoes deformation at a predetermined gas pressure in the housing of the tap head and a gap for the release of excess gas pressure is formed between the plate and the annular seal.

Abstract: A tap head for keg fittings having an actuating lever pivotally mounted on a housing and connected to a slide movable in the housing and detent members positively engaging in one another to lock the actuating lever and with one of the detent members directly biased toward the stop position and in which the detent members are formed of plastic and are made up of an elastically self-biasing tongue cooperating with a detent edge with one of the tongue and detent edge formed integrally on the housing and the other of the tongue and detent edge integrally formed on the actuating lever and with connections for gas and liquid connectable via the slide with corresponding passages in the keg fittings.

Abstract: A pinchcock comprises a housing, a tube section of elastically flexible material arranged in the housing, a pinching element displaceable in the housing in a direction extending transversely to the longitudinal axis of the tube section and engaging on the outer side of the tube section and an actuating member for displacing the pinching element. The housing is designed as a plastic molded part, in which a ball is displaceable, as pinching element, in the direction extending transversely to the longitudinal axis of the tube section. The actuating member comprises a cam engaging the ball, this cam being rotatable about an axis aligned at right angles to the longitudinal axis of the tube section and to the direction of displacement of the ball.

Abstract: A device for tapping beer or the like from cans comprises a housing with an outlet closable by a tapping valve and an air pump. Attached to the housing is a piercing pipe which can be introduced into the can and forms a beer discharge channel which is in communication with the outlet. The air supplied by the air pump flows separately from the beer through lateral air outlet openings of the piercing pipe into the can above the level of the beer and applies pressure to the beer. The flow cross-section of the beer discharge channel in the piercing pipe is determined substantially throughout its entire length by the internal diameter of this pipe. A thin-walled sleeve of smaller external diameter than the internal diameter of the piercing pipe which separates the beer discharge channel from the flow path of the supplied air and which is sealed relative to this channel below the air outlet openings is provided in the upper region only of the piercing pipe.
