Abstract:
An apparatus for volumetric metering of small quantities of product from a reservoir (12) and dispensing the product into containers (a), comprising a metering disk (11) in a bottom of said reservoir (12) that revolves about a vertical axis (13), said metering disk includes a plurality of metering chambers (15) which are disposed in multiple groups on a pitch circle and are open at the top and closable at the bottom by a pusher (17), one pusher (17) for each group of metering chambers, each of said metering chambers are filled by sweeping in a product above the pusher and evacuated by openings (18) in said pusher at a filling station in congruence with the containers (a), in that one pusher (17) is provided for each metering chamber groups, each pusher (17) is provided with apertures (18), one each for each metering chamber (15) of each group, and each of said pushers (17) is disposed displaceably on an underside of the metering disk (11), in such a way that the apertures (18) are offset from the metering chambers (15) in the filling position; that the pushers (17), beginning at the filling position, are rotated jointly with the metering disk (11) in a direction of an evacuation station; and upon reaching the evacuation station, the pushers (17) are displaced by stop means (31, 33) relative to the metering disk (11), so that the metering chambers (15) and the apertures (18) coincide in the evacuation position.
