Abstract
In an arrangement for a filling valve on a packing machine after-dripping is prevented by providing that the outside surfaces of the valve which can come into contact with the contents are cleaned with the help of a pressure fluid during operation of the machine. An arrangement in accordance comprises a filling valve whose valve body is provided with a channel for the supply of pressure fluid and an outlet opening situated at the lower end of the valve body which conducts the pressure fluid and causes it to flow along the underside of the valve body so that any residue of the contents is effectively flushed away.
