Abstract
The invention relates to a metering device for insertion into the mouth of a liquid container comprising an elongated cylinder having a cylindrical outlet opening extending beyond the mouth of said liquid container and one or more openings at the other end communicating with the interior of said liquid container, a metering chamber in said elongated cylinder, toward said outlet opening, a ball valve chamber in said elongated cylinder and a ball valve between the interior of the container and the metering chamber. The ball valve consisting of a valve ball and its seat is situated at the inlet opening of the metering chamber on the container side. In order always to obtain the same metered quantity irrespective of the tilting speed and the hydrostatic pressure which is determined by the filling level of the container, the valve ball is connected by a piston rod to a piston mounted for displacement in the cylindrical outlet opening of the metering chamber.
