Pump and actuator assembly for a self-inflating tire

A system comprising:

• a tire comprising a tire cavity defined by an inner liner, first and second sidewalls extending, respectively, from first and second tire beads to a tread;
• a compression actuator means mounted within the tire cavity for delivering air to the tire cavity, the compression actuator means comprising a containment body formed from a resilient deformable material and containing a quantity of a non-compressible medium, the containment body affixed to one of the first and second sidewalls and reciprocally transforming with the sidewall between a deformed state and a non-deformed state responsive to deformation and recovery of the tire sidewall of the rotating tire, the containment body, in the deformed state, displacing the non-compressible medium thereby generating a compression force delivering a volume of air to the tire cavity, the containment body operationally undergoing a cyclic deformation between the deformed state and the non-deformed state responsive to rotation of the tire, the containment body being shaped to facilitate pivoting during rotation of the tire;
• and
• a pump assembly connected to the containment body and mounted within the tire cavity, the pump assembly comprising a compressor body with an air chamber, the air chamber having an inlet opening for admitting air into the air chamber and an outlet opening for conducting a pressurized quantity of air from the air chamber to the tire cavity, the compressor body positioned to one of the first and second sidewalls radially inward from the containment body.
