ABSTRACT:
A device for maintaining inflation pressure within a tire interior of a tire mounted on a rotating wheel with a rim. The device includes a compressor with piston penetrateably mountable on the wheel rim or in communication with a valve stem that incorporates air delivery to the compressor as mounted within the tire. The piston is in communication with a compressible piston driver having a distal end in contact with the inner floor of the mounted tire where the outer side of the tire contacts the ground once every revolution of the wheel. Repeated deformation of the rotating tire where it contacts the ground outside the distal end of the driver is transferred to the air compressor through a piston compression stroke. When such ground contact is not occurring, centrifugal force causes radial movement to accomplish the intake stroke of the piston. In this repetitious manner a small amount of air is forced into the tire during each rotation thereof when needed to maintain desired inflation pressure.
