ABSTRACT:
An improved portioning assembly adapted for use in the precise portioning of food or other products is provided which makes use of a double-acting piston and cylinder assembly shiftable between defined limits, with the stroke length of the piston being correlated with the quantity of dispensed portions. The preferred overall portioning assembly includes a hydraulically operated product pump coupled with the control piston and cylinder assembly for sequential product-dispensing movement thereof; movement of the control piston between spaced limits serves to actuate associated limit switches, the latter operating a valve for directing pressurized charges of hydraulic fluid to the hydraulic pumping chamber. If desired, a delay can be provided before the initiation of each product-dispensing stroke of the control piston.
