Abstract: A nozzle assembly (44) for a filling machine, the nozzle assembly controlling foaming and dripping of the product during and after the filling operation. The nozzle assembly includes a nozzle body (46), a fixed filling tube (48), a movable tube assembly (50), and movable cam structure (52). The movable tube assembly is provided with a sealing foot (80) through which a bore extends, the body being interconnectable with a vacuum line (66) after the completion of the filling of a container (16) to prevent dripping on the container. The movement of the movable tube assembly (50) is controlled by gear structure (100) associated with a valve (38) which controls the discharge of material through the nozzle assembly, in such a manner that the nozzle assembly will be closed when the valve is closed.

Abstract: A rotatable valve assembly (38) for a rotary piston filling machine, the rotatable valve assembly being received within a valve body (30). The valve assembly includes a supporting valve plug (40) and interchangeable valve sleeves (42) which are adapted to be telescoped over the valve plug to an assembled position. Alignment means in the form of pins (152) and apertures (154) maintain the sleeve (42) in its desired assembled relationship on the plug (40) and insures that the valve sleeve (42) will rotate with the valve plug (40). The parts can be readily disassembled for cleaning. The valve sleeve (42) may be formed of polytetrafluoroethylene or of Waukesha Metal. The valve plug is preferably made of a stainless steel suitable for use in the food industry.
