ABSTRACT:
A metering device for flowable products, in particular, dairy products, is provided with a metering cylinder, a valve cylinder connected to the reservoir, a metering piston that is movable between an upper intake end position and a lower dispensing end position, and also has a mouthpiece closing the bottom of the metering chamber and having a coaxial cylindrical dispensing opening, and a central valve piston. The valve cylinder and the valve piston form a rotary control unit which, in a first rotary position, connects the metering chamber with a supply channel in the valve cylinder and, in a second rotary position, connects the metering chamber to an outlet channel.
