ABSTRACT:
A hermetically sealed twin rotary compressor is disclosed wherein a pair of rotary vane compressors are synchronously, coaxially coupled to respective axial ends of a drive motor by means of a quill disposed in a rotation rotor thereof. The rotary compressor crankshafts are coupled to the quill with their eccentric portion oriented opposite one another with respect to the axis of rotation. Counterbalancing weights are mounted to the motor end rings oppositely the adjacent eccentric portion with respect to the axis of rotation. A suction accumulator is provided having a pair of tubes extending from fluid outlets on the accumulator to respective fluid inlets associated with the pair of compressors. The tubes pass through a pair of spaced apertures in the housing and effectively mount the suction accumulator to the housing. A method of assembling the compressor assembly, including accumulator, is also disclosed.
