  • Patent number: 6223955
    Abstract: The invention relates to a tapping head with a cylinder cavity in which a plunger is arranged. The plunger is capable of moving up and down and is biased or loadable by a coil spring. The tapping head consists of a barrel connection housing connected with the cylinder cavity of the tapping head housing, a rising tube extending through the housing and the plunger and forming a channel for the beverage. The tapping head also has a slidingly arranged, sleeve-like tappet connected to the plunger and a connection for cleaning liquid. The connection for the cleaning liquid feeds into the tapping head housing in an annular gap between the rising tube and a tube surrounding the rising tube, and is connected there with the rising tube (rinsing position) or sealed by a seal (tapping position) depending on the position of the tappet. A transversely extending gas line is arranged in the plunger.
