Washing device for rotary filling machine

Image Number 3 for United States Patent #4024896.

A washing device for a rotary filling machine which device is provided with the same number of washing liquid pipes as the number of filling nozzles. During the usual filling step, the washing liquid pipes are positioned so as not to interrupt the movement of the bottles to be filled. During the washing step, the washing liquid pipes are positioned directly below the filling nozzles. The washing liquid pipes are then brought close to and pressed against said filling nozzles, the valves mounted in said filling nozzles are pushed open by the tip ends of said washing liquid pipes, and thereby the flow passages for the filling liquid including the inner parts of said filling nozzles are washed with a washing liquid.
