  • Patent number: 5244127
    Abstract: A keg tap for dispensing a pressurized liquid from a container having a keg closure includes a substantially cylindrical housing which defines a pressure chamber within the housing. An axially movable valve-opening rod is inserted through the housing and pressure chamber and has one end which engages the keg closure. The rod has a continuous liquid passage extending from end to end and connecting at right angles with a liquid canal. A bracket supports the liquid canal and engages the rod so that the bracket and the rod are jointly raised and lowered. The rod extends through an insert in a lower end of the housing, the insert having bores arranged therein for receiving pins on a fork connected to a movable lever. The rod includes upper and lower flanges which define a groove therebetween for engaging another set of pins on the fork. The rod is upwardly and downwardly movable by moving the lever.
