ABSTRACT:
A rotary face valve for beverage filling machines provides a housing assembly defining a closed chamber. The stationary valving surface is provided open to the chamber, and a valve rotor is journaled in the chamber in engagement with the stationary valve surface. The chamber is pressurized to a pressure closely approaching the pressure of the beverage being valved so that a low differential pressure exists between the chamber and the port through which the beverage flows. This minimizes the tendency to encounter leakage. The rotor is supported by a shaft which is journaled in spaced bearings so that eccentric force applied to the operating shaft is absorbed by the bearings and is not transmitted to the rotor. Further, the rotor is connected to the operating shaft with sufficient freedom to ensure that the rotor properly engages the valve surface in a uniform manner. A drain is provided for the rotor chamber so that any leakage which might occur into the chamber can be drained from the valve without contaminating the adjacent portions of the machine.
