Abstract

Isobaric rotary filling machine for filling containers, has a rotating table supporting a pressurized tank and valve units. Each valve unit has a filling duct for supplying the liquid from the tank to the containers, regulated by a faucet, and an air return pipe associated with a shut-off valve for controlling the pressure balance between the container and the tank. A flushing station, operationally associated with but fixed relative to the rotating table, has a receiving tray connected to a flushing circuit and operable to move between a non-operative position situated outside the travel path of the valve units, and an operative position situated underneath the travel path. The faucets and the shut-off valves open each filling duct and each pipe when the receiving tray is in the operative position and the flushing circuit is connected to the supply line of the tank.
