Hermetic compressor assembly having a suction chamber and twin axially disposed discharge chambers

A hermetic rotary compressor assembly, comprising:

• a housing;
• a pair of spaced apart main bearings disposed within said housing, said pair of main bearings subdividing said housing into first and second discharge chambers and a suction chamber, said suction chamber disposed between said pair of main bearings and said discharge chambers, each said discharge chamber including a pool of lubrication oil disposed therein;
• first and second compressor mechanisms disposed respectively in said discharge chambers, each said compressor mechanism comprising an outboard bearing, a cylinder block disposed between respective said outboard and main bearings and defining a cylindrical cavity, a roller piston in said cylindrical cavity, a vane supported in said cylinder block and rotationally engaged by said roller piston, a suction port and at least one discharge opening in fluid communication with the respective said discharge chamber;
• a drive motor disposed in said suction chamber;
• a drive shaft drivingly connected between each said roller piston and said motor;
• at least one of said suction ports extending through the respective said main bearing;
• and
• a pair of discharge conduits connected respectively to said pair of discharge chambers to convey discharge gases therefrom, one of said discharge conduits fluidly communicating said first and second discharge chambers, said pools of lubrication oil redistributable between said first and second discharge chambers through said one of said discharge conduits.
