Abstract
A compressed air delivery system in which power from a power supply is transmitted to a rotary air compressor through a dry running, continuous variable transmission (CVT) utilizing a belt coupled between two pulleys enclosed within a CVT housing. The air pressure differential created by the rotary air compressor is used to urge cooling air through the CVT to cool the CVT belt. The pressure differential may be utilized to push cooling air into the CVT housing or to draw cooling air through the CVT housing. In one embodiment, a portion of the compressed air discharged from a supercharger may be routed through a bleed line and into the CVT housing.
