Abstract
A high pressure electromagnetic reciprocating fluid pump is disclosed herein. The pump has a pair of telescoping cylinders axially disposed inside a generally cylindrical cavity of a pump housing. Unidirectional valves disposed at the opposing ends of the telescoping cylinders cause a unidirectional fluid flow through the pump as the telescoping cylinders are reciprocated relative to each other by a solenoid driven armature.
