Filling valves for cans and like containers

A counter-pressure type filling valve mechanism for cans and analogous containers, comprising:

• a hollow, tubular housing;
• a generally cylindrical sleeve mounted co-axially of said housing for vertical movement relatively thereto and provided with a resiliently deformable sealing ring adapted to be received within and to engage outwardly against the inner wall surface of the container upon the sleeve being lowered on the housing whereby to seal the container to the valve mechanism;
• said sleeve being further provided with resiliently compressible stripping means adapted to yieldingly engage the container upon the sleeve being lowered to the container whereby to forcibly constrain the container against movement with the sleeve upon the latter being moved to a raised position on the housing following the filling of the container with liquid;
• stop means formed integrally with said housing for limiting the sleeve for downward slide movement on the housing, the limit position being such as to permit the sealing ring means to enter into and sealingly engage the container and stripping means to yieldingly engage the container prior to the sleeve engaging said stop means;
• and
• roller means associated with the sleeve for controllably moving the latter between raised and lowered positions on said housing during the course of a container filling cycle.
