Abstract
A device for metering out a flowable mass, especially a mass containing fat, for producing confectionery products, for example to a nozzle for extruding a mass into a mold. The mass traverses an inlet opening (13) and enters a chamber (8) from where it can be extruded through an outlet opening (14) by a plunger (7). A rotary piston (12) is associated with the plunger (7) and closes the outlet opening (14) in a position of use and the inlet opening (13) in a second position of use. The rotary piston (12) has a recessed portion (16 to 19) which extends from a front edge (15) of the rotary piston (12) towards its peripheral surface (25).

1-17. (canceled)
A device for metering a flowable mass comprising:
- a pump comprising a housing defining a chamber having an inlet and an outlet, a rotary piston having a passage and a surface, said rotary piston being positioned in the chamber for rotary movement about an axis A in the chamber between (1) a first position wherein an inlet communicates with the chamber through a passage in the rotary piston and an outlet is closed to the chamber by a surface of the rotary piston and (2) a second position wherein the inlet is closed to the chamber by the surface of the rotary piston and the outlet communicates with the chamber through the passage in the rotary piston, a plunger mounted in the chamber in opposition to the rotary piston and defining with the housing and the rotary piston a pump chamber, a lifting bar movable in a direction along axis A toward and away the rotary piston for moving the flowable mass from the inlet to the outlet.
