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. The centrifuging assembly is constructed so that the liquid refrigerant and oil are collected in a chamber having a pressure greater than the pressure in the lower chamber, thereby creating a pressure differential between the liquid containing chamber and oil sump in the lower chamber to force the collected liquids through a plurality of passageways communicating between the liquid collecting chamber and the lower chamber. The gaseous refrigerant is then delivered to a four cylinder scotch-yoke arrangement for compression and discharge to an external refrigerant cooler for cooling the compressed gas. The cooled gaseous refrigerant is then delivered to the upper chamber for cooling cylinder heads and ultimate discharge from the compressor. An oil pump assembly in the bottom of the lower chamber pumps the collected oil out of the compressor and through an oil cooler to cool the oil. The cooled oil is then returned to the oil pump assembly for delivery throughout the compressor to lubricate and cool components therein.
