Abstract
A sealing valve arrangement for dispensing apparatus having a turntable rotatably mounted on a support includes a valve with an outwardly protruding operator member with a free end remote from the valve, and a valve mount for mounting the valve to the turntable mount for travel with the turntable. A cam block mounted stationary on the turntable support defines a channel for receiving the free end of the operator member and, with rotation of the turntable, moves the operator member so that the valves move from one position to another.
