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.

Claim (Index 3):
A method of assembling a pump system with a container, comprising:\n assembling a pump engine at a first location wherein the pump engine comprises:\n an accumulator cup having a product chamber; \n a valve ball; \n an output cylinder defining a cavity therein; \n a spring; \n a piston seal; and \n a piston stem having a fluid lock at one end and a piston stem flange at an opposing end, \n said step of assembling said pump engine comprising the steps of:\n inserting the spring into the output cylinder; \n inserting the piston stem through the output cylinder such that the fluid lock extends through an opening in the bottom of the output cylinder and the spring is captured between the output cylinder and the piston stem flange; \n press fitting the piston seal over the fluid lock of the piston stem to secure the piston seal to the piston stem; \n inserting said valve ball into a valve seat in a bottom wall of the accumulator cup; \n removably attaching the output cylinder to the accumulator cup by interfitting snap-fit latch structures to form the pump engine; \n snap fitting the pump engine with a closure; snap fitting a pump head with the upper end of the piston stem whereby the pump head is in fluid communication with the piston stem and is movable relative to the closure; placing a gasket around the outside accumulator cup and within the closure; inserting a dip tube into a clip tube receptacle on a bottom wall of the accumulator cup to form a pump system; and assembling said pump system with a container at a second location comprising the steps of: assembling the closure of the pump system with a neck of a container whereby the gasket forms a seal between the container neck and the closure.
