Patent abstract
A pump engine assembly includes an output cylinder that may be customized to include a stop portion limiting the stroke of a piston to produce a particular output such that customized pump systems may be produced from similar parts with the exchange of only a single part—the output cylinder, and wherein movement of a fluid lock in a product chamber creates a suck-back feature capable of pulling product away from a dispensing head opening.
