FILLING VALVE

摘要

A filling valve wherein a piston is mounted for angular movement about a vertical axis immediately above a thin bottom wall of a housing which defines a metering chamber for a flowable material to be introduced into a succession of vessels. The material which is to be dispensed flows from a metering chamber in the housing through one or more channels in the piston and into and from dispensing openings in the bottom wall. The bottom surface of the piston has sharp sealing edges which slide along the upper side of the bottom wall and shear off the flow of material at the outlets of the channels when the piston is turned to a position in which the outlets of the channels are sealed from the dispensing openings in the bottom wall. This prevents dripping of flowable material in such position of the piston.
