ABSTRACT:
A dispensing valve is provided for dispensing metered quantities of liquid and semi-solid food products from a hopper or reservoir.The valve has a piston and piston rod reciprocating in a rotatable sleeve to which it is keyed and the latter being journaled for rotation coaxially within a cylindrical valve housing. By rotating and reciprocating a handle attached to the piston rod a transfer port in the sleeve is selectively positioned in registry with intake and discharge ports in the housing to fill the sleeve with food on the intake stroke of the piston and discharge the food from the sleeve on the discharge stroke of the piston. Bosses are selectively placed on the piston rod between the handle and the housing to vary the stroke of the piston and thus, the measured quantities of food ingested and dispensed by the valve.
