<p>PURPOSE: A dual capacity compressor is provided to stably work keeping fixed eccentric degree while rotating action for changing capacity. CONSTITUTION: A compressor comprises a power generating part including a motor capable of reverse rotation, and a crankshaft(23) inserted to the motor; a compression part including a cylinder, a piston placed in the cylinder, and a connecting rod(33) connected with the piston; a crank pin(110) formed on an upper end of the crankshaft eccentrically with a center of the crankshaft; an eccentric sleeve(120) having an inner circumferential surface joined to a periphery of the crank pin to rotate and a periphery to which an end of the connecting rod is joined to rotate, and re-arranged according to rotating direction of the motor to change effective eccentric degree between the crank pin and the connecting rod; and a fixing member(130) completely fixing the eccentric sleeve to the crank pin.</p> |
