Abstract

An air pump is a dual action manually driven with a piston and two intake and two exhaust check values that respectively operate with one intake port and one exhaust port. These check valves operate in tandem with each other during each pumping stroke, either up or down. During each pumping stroke, one intake check valve and one exhaust check valve are open with their counterparts closed, to provide continuous discharge of compressed air through the exhaust port and also to provide continuous intake of air through the intake port. The air pump includes a cylindrically shaped hollow reservoir housing, a base connected to one end of the housing, an intake port and an exhaust or inflate port which are mounted on the base, an elongated piston shaft extending along the longitudinal axis of the housing, and a handle perpendicularly disposed with respect to the piston shaft to assist pumping of the piston shaft.
