摘要： A dual capacity compressor, which can maintain a fixed eccentricity and stable operation, even when the compressor is rotated in both the regular and reverse directions in order to provide multiple compression capacities, is provided. This dual capacity compressor implements an improved key member and associated key member fitting parts to inhibit relative motion of the crank pin and the eccentric sleeve during operation, so as to reduce or eliminate a destabilizing effect due to centrifugal forces on the eccentric sleeve and external forces applied through the connecting rod.

摘要： Dual capacity compressor is provided to prevent relative movement between parts that maintain eccentricity. To this end, the dual capacity compressor comprises a power generating unit 20, having a reversible motor 21 and 22 and a crank shaft 23 inserted into the motor 21 and 22; a compressing unit 30 having a cylinder 32, a piston 31 and a connecting rod 33 connected with the piston 31; a crank pin 110 and 210 eccentrically formed on an upper end portion of the crank shaft 23; an eccentric sleeve 120 and 220 mounted between the crank pin 110 and 210 and one end of the connecting rod 33; and a key member 130 and 230 for completely restricting the eccentric sleeve 120 and 220 to the crank pin 110 and 210 in both clockwise and counter clockwise direction rotations of the motor.
