Abstract

Official abstract text for this publication.

A drain valve for draining liquid out of a container which comprises an essentially cylindrical opening that passes through a thickened area of the container wall, with an internally threaded section formed at an outer end thereof, followed by an interior space with a larger diameter into which a duct opens, and opposite the interior space an inner section with a smaller diameter opens into the container. A step is provided between the interior space and the inner section and serves as the seat for an associated end face of the valve element. A step between the interior space and the bore, on the one hand, and the inner end face of the valve element, on the other hand, are designed to co-operate as a valve seat which progressively opens and closes as the valve element is displaced.
