Abstract: A direct suction radial compressor having a crankcase therein dividing the compressor into an upper chamber and a lower chamber sealed one from the other, and suction inlet tubing extending through the top portion of the upper chamber for delivering refrigerant to the compressor. A suction chamber is disposed in the crankcase and sealed from the upper chamber and in communication with the suction inlet tubing, and a plurality of radially disposed cylinders are disposed in the crankcase. Positioned between the suction inlet and the cylinders is a centrifuging assembly that separates liquid refrigerant and oil from gaseous refrigerant, and returns the liquids through a unique network of passageways to an oil sump in the lower chamber.
