Abstract
A compressor is provided that includes a supplementary torque providing part that reduces a speed of a piston compression of refrigerant and increases the speed of the piston in drawing of the refrigerant. This structure reduces a compression rate of the refrigerant in compression relatively, and increases a re-expansion rate, to maximize suction efficiency.
