Abstract
A hermetic compressor assembly having a housing and a pair of spaced apart main bearings, disposed within the housing, which subdivide the housing into first and second discharge chambers, and a suction chamber. The suction chamber is disposed between the pair of main bearings and first and second compressor mechanisms are disposed, respectively, in the discharge chambers. Each compressor mechanism has an outboard bearing, a cylinder block, which is disposed between the outboard and main bearings and defining a cylindrical cavity, a roller piston in the cylindrical cavity and a vane supported in the cylinder block and rotationally engaging the roller piston. At least one discharge opening is in fluid communication with the respective discharge chamber and a drive motor is disposed in the suction chamber. A drive shaft drivingly connects each roller piston to the motor. A suction port is disposed within at least one of the compressor mechanisms and extends through the respective main bearing. A pair of discharge conduits are connected, respectively, to the pair of discharge chambers to convey discharge gases therefrom.
