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.
