Abstract:
1. A tire pressurization system configured to mount to a wheel having a rotational axis, the system comprising: a casing configured to mount to the wheel; a first compressor mounted to the casing and configured to fluidly connect to a fluid source, the first compressor comprising a first chamber and a first actuating element, the first actuating element having a first area; a second compressor mounted to the casing, fluidly connected to the first compressor and configured to fluidly connect to a tire interior, the second compressor comprising a second chamber and a second actuating element, the second actuating element having a second area; and a passive drive mechanism mounted to the casing and configured to actuate the second compressor between a compressed state and a recovered state, the passive drive mechanism comprising an eccentric mass configured to mount to the wheel with a center of mass offset from the rotational axis, wherein relative rotation between the eccentric mass and the second compressor actuates the second compressor between the compressed state and the recovered state.
