Abstract: A compressor according to the present invention comprises a hinge recess formed at a rolling piston and a hinge protrusion formed at a vane to be inserted into the hinge recess. A diameter of the hinge protrusion is greater than an interval between both ends of an opening of the hinge recess. A bearing surface, which comes in contact with an inner circumferential surface of the hinge recess, of an outer circumferential surface of the hinge protrusion, has a circumferential surface below 90° at both sides, respectively, based on a central line in a lengthwise direction of the vane. This structure may facilitate for cutting and grinding the bearing surface so as to reduce a machining cost, and also improve a machining degree and thus stabilize behaviors of the rolling piston and the vane so as to enhance compression efficiency.

Abstract: Disclosed is a compressor having a torque load reducing unit for moving a center of weight to which a gas force is applied. 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 becomes short. This can reduce a torque load to the roller, and can enhance compression efficiency.

Abstract: A compressor is provided that may include a passage separator (8) provided between an electric motor drive (2) and a compression device (3) to separate a refrigerant passage from an oil passage. The passage separator (8) may include a first partition wall (82) and a second partition wall (84). The first partition wall may be disposed between an inner circumferential surface of a casing (1) and a discharge hole (314b,322a) of the compression device, and the second partition wall may be disposed between the discharge hole and a balance weight (7). Accordingly, the refrigerant passage may be separated from the oil passage between the compression device and electric motor drive, thereby efficiently recovering oil to an oil storage space (V3).
