ABSTRACT:
This invention pertains to the maintenance of pressure within a vehicle wheel tire to a pre-set level with the air supply being produced by a pump which is driven by centrifugal force, i.e., the wheel rotation creates a centrifugal force which activates a weight to move a piston which pumps the tire inlet air. The pump can be mounted outside or inside the tire volume. Another pump uses the impetus from bumps encountered by the wheel to drive the pump.
