Abstract
In a bottle filling machine having a toroidal liquid tank and several filling units arranged circularly about the tank, each filling unit has a support which can be moved radially by means of an actuator. Each movable support supports a liquid flow inverter cup which can be connected to the filling unit for closing the opening of the gas return tube of the unit when cleansing solution is circulated through gas and liquid passageways of the machine. The converter cup, during a normal filling operation, is parked behind a circular barrier wall which is mounted radially inwardly from the filling units for surrounding the inverter cups and their movable support members during normal bottle filling operations. There is a doorway hole in the barrier wall aligned with each movable inverter cup support and a door is mounted to the movable support so that it keeps the doorway closed during regular bottle filling operations. In this way, the movable supports and the inverter cups thereon are protected against damage and soiling when they are in parked position.
