Abstract

A control valve suitable for use with a tire and pump assembly is described that controls the flow of air from the pump into the tire. The control valve includes an optional bi-directional feature. The pathways alternatively operate to deliver ambient non-pressurized air to the air pumping tube in response to directional tire rotation against a ground surface.
