Abstract:
1. A compressor assembly, comprising: a compressor for compressing a gas, the compressor including a piston reciprocated in a cylinder and a compressor shaft; a motor assembly for providing motive force to the compressor, the motor assembly including a motor shaft; and a belt drive for coupling the motor shaft to the compressor shaft for reciprocating the piston within the cylinder, the belt drive including: a belt; a flywheel mounted to the compressor shaft and coupled to the piston: a motor sprocket mounted to the motor shaft; and a belt idler, the flywheel and belt idler receiving the belt so that the belt passes over the motor sprocket and is driven by the motor sprocket, wherein the belt drive provides a reduction in the speed of rotation between the motor shaft and the compressor shaft and causes the compressor shaft to rotate in a direction opposite the motor shaft.
