ABSTRACT:
A volumetric metering apparatus which provides a continuous succession of accurately metered deposits of baking dough or other flowable media. Media is fed into a cavity in the apparatus. The cavity is in fluid communication with an outlet. A valve is disposed in the cavity so as to define first and second chambers therein. The valve is movable between a first position where the first chamber is in fluid communication with the outlet and a second position where the second chamber is in fluid communication with the outlet. A piston device disposed in the cavity and operatively associated with the valve alternatingly discharges media from each chamber when the chamber is in communication with the discharge orifice.
