Abstract: A hermetically sealed scotch yoke compressor assembly is disclosed wherein a crankcase includes annular channels formed on the top and bottom surfaces thereof defining muffling chambers. Gas refrigerant compressed within radially disposed cylinders into cylinder head covers is channeled into the upper annular muffler chamber and them through passages extending through the crankcase into the lower muffling chamber. An annular cover plate for covering the bottom annular channel is attached to the crankcase at its radially inner extreme and is biased against the crankcase at its radially outer extreme. Spacers between the cover plate and the crankcase provide an annular discharge opening directing discharge gas onto the motor windings.

Abstract: A compressor assembly including a compressor mechanism mounted within a hermetically sealed housing. The compressor mechanism includes a crankcase having a suction inlet opening providing communication into a suction cavity within the crankcase. A suction line adaptor is provided for attaching to a suction line of a refrigeration system to introduce suction gas from the exterior of the housing to the suction inlet opening within. The suction line connector includes a fitting mounted to the housing sidewall and having a bore communicating therethrough, and a tube insert extending between the fitting and the suction inlet opening. The tube insert includes annular protuberances at opposite ends thereof, each protuberance having a groove into which an O-ring seal is retained. The opposite ends of the tube insert are sealingly received within the fitting bore and the suction inlet opening, respectively, whereby limited axial, radial, and torsional movement of the compressor mechanism relative to the housing is permitted while maintaining the integrity of the suction tube connector against leakage from the interior of the housing.

Abstract: A direct suction hermetic compressor assembly is disclosed including a hermetically sealed housing having enclosed therein a compressor mechanism discharging compressed gas refrigerant into the interior of the housing, thereby creating a high pressure housing. The compressor mechanism includes a crankcase defining a suction cavity into which low pressure suction gas is directly introduced. Bearings in the crankcase communicate between the housing interior and the suction cavity, and rotatably support a crankshaft. Annular seals received within grooves in the crankshaft bear against the bearings and are actuated and lubricated by oil fed from within the grooves to prevent high to low pressure gas leakage and to facilitate bearing lubrication. A scotch yoke mechanism operably couples a plurality of radially disposed pistons to a crankshaft eccentric portion within the suction cavity. Oil ducts open onto the loaded surface of the eccentric to limit oil leakage into the suction cavity.

Abstract: A suction accumulator for the compressor of a refrigeration system is disclosed in which a suction tube connected to the outlet of the accumulator extends vertically within the accumulator vessel and has liquid metering openings located adjacent to the bottom of the vessel and as gas inlet openings located adjacent to the top of the vessel between the liquid metering openings and the accumulator outlet along the length of the suction tube. A float valve member surrounds the suction tube and is slidable along the vertical length thereof. In response to the accumulation of liquid refrigerant, the valve member covers the gas inlet openings to prevent introduction of liquid refrigerant therethrough. Extension of the gas inlet opening along the vertical length of the suction tube provides progressive opening and closing by the valve member in response to changes in liquid accumulation.

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. 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.
