Abstract
The centering nozzles of continuously orbiting material-supplying valves in a filling machine wherein cans, bottles or other types of containers are moved into register with and advance with the valves in the course of the filling operation are biased toward the material-receiving portions of registering containers by mechanical springs or by pneumatic cylinder and piston units in order to ensure that the nozzles can yield when necessary so as to preserve the integrity of the valves and/or of the containers. The springs and/or the cylinder and piston units are interposed between the nozzles and the assemblies which serve to raise and lower the nozzles relative to the containers below them. The nozzles also serve as differential pistons to bias their sealing elements against the adjacent containers during actual admission of a flowable material.
