Abstract: Dual capacity compressor including a power generating part ( 20 ) having a reversible motor ( 21, 22 ) and a crank shaft ( 23 ) inserted in the motor ( 21, 23 ), a compression part ( 30 ) having a cylinder ( 32 ), a piston ( 31 ), and a connecting rod ( 33 ), a crank pin ( 110 ) in an upper part of the crank shaft ( 23 ) eccentric to an axis of the crank shaft, an eccentric sleeve ( 120 ) rotatably fitted to the crank pin ( 110 ), and the connecting rod ( 33 ) respectively, a key member ( 130 ) for positive fastening of the eccentric sleeve ( 120 ) to the crank pin ( 110 ) in all rotation directions of the motor, and an eccentric mass ( 200 ) provided to the eccentric sleeve ( 120 ) for rotating the eccentric sleeve ( 120 ) around the crank pin ( 110 ), thereby preventing relative motion between components that sustain the eccentricity, and permitting a smooth motion between the components.

Abstract: A crankshaft in a dual capacity compressor is disclosed, which causes oil contained in a lower portion of the compressor to flow up to an upper portion thereof with respect to all the rotational directions of a motor. A crank shaft ( 100 ) includes a driving shaft ( 110 ) inserted into a reversible motor ( 21, 22 ) for rotating along with the motor ( 21, 22 ), a balance weight ( 120 ) formed in a top portion of the driving shaft ( 110 ) for preventing vibration during rotation from occurring, a crank pin ( 130 ) formed on an upper surface of the balance weight ( 120 ) to be eccentric from the center of the driving shaft ( 110 ), and a regular/reverse oil path ( 140 ) formed along the balance weight ( 120 ) and the crank pin ( 130 ) for moving oil for forward rotation and reverse rotation of the motor respectively. The crankshaft serves to stably lubricate each driving part of the dual capacity compressor regardless of rotation direction.
