Abstract
A compressor having a torque load reducing unit to move a center of weight to which a gas force is applied is provided. As the torque load reducing unit is formed at an oval-shaped roller, a distance between a rotation center of the roller and an operation point to which a gas force is applied is shortened. This may reduce a torque load to the roller, and may enhance a compression efficiency.
