More Information
Summary:The present invention relates to a dual capacity compressor for preventing relative movement from taking place between components. For this, the present invention provides a dual capacity compressor including a power generating part (20) having a reversible motor (21, or 22) and a crank shaft (23) inserted in the motor (21, or 22), 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 from an axis of the crank shaft (23), an eccentric sleeve (120) rotatably fitted between the crank pin (110) and an end of the connecting rod (33), a key member (130, or 230) configured such that the key member is held at at least a part of the eccentric sleeve (120), and held at the eccentric sleeve (120) additionally during operation, for latching the eccentric sleeve (120) with the crank pin (110) positively in both direction rotation of the motor.
