Abstract
A wheel valve assembly for adjusting the air pressure within a pneumatic tire is provided that includes a body that extends from a first end in communication with a pressure source to a second end in communication with the tire. A low pressure differential operable valve member is received within the body. The valve member is moveable between open and closed positions for respectively allowing and preventing air communication between the internal segment and the external segment of the body. The check valve of the present invention is virtually unaffected by the centrifugal force of a rotating tire to substantially prevent back flow of the tire air when the tire is rotating at a relatively high speed.
