  • Patent number: 4573486
    Abstract: For cleaning container filling machines through utilization of cleaning-in-place (C.I.P.) canisters that are inserted between rotating filling valves and their matching lift cylinders, the lift cylinders are arrested in their lowest end position by the C.I.P. canisters acting as spacers to allow the cam follower rollers to pass under the stationary lifting cam at a slight distance, while the C.I.P. canisters are held against the filling valve under pressure. The C.I.P. canisters thus remain pressed against the filling valves during the full rotation of the filling machine without the follower rollers being acted on by the lift cam.
