SYSTEMS AND METHODS FOR PROVIDING A DYNAMICALLY ADJUSTABLE RECIPROCATING FLUID DISPENSER

摘要

A reciprocating fluid dispenser including a pump drive motor (50) which is coupled to a reciprocating fluid pump (42) to actuate a pump shaft (72) within a pump cylinder (60), wherein the pump shaft includes a duct (76) that allows fluid to selectively pass thereby within the pump cylinder. As the pump shaft rotates within the pump cylinder, fluid is allowed to enter into a pump bore defined by a portion of the pump cylinder through a pump ingress port and be dispensed through a pump egress port. An adjustment motor (52) is coupled to an adjustment mechanism which selectively adjusts the volume of the pump.
