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 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: A scroll compressor includes an oil recollecting pump for recollecting oil discharged from a shell, thus to effectively recollect oil discharged out of the compressor. A differential pressure hole is formed at a position where it communicates with compression chambers after a suction completion timing such that oil stored in an inner space of the shell can be supplied into the compression chambers using pressure difference between the high-pressure inner space of the shell and the low-pressure compression chambers, resulting in allowing oil to be smoothly supplied to a compression unit even during low-speed driving of the compressor and preventing beforehand an occurrence of a suction loss due to oil.

Abstract: A hermetic compressor includes a vane that is inserted into the roller, rotates with the roller, and is pushed out toward the inner circumference of the cylinder by the rotation of the roller to divide the compression chamber into a plurality of spaces, the vane including: a body portion that has a sealing surface contacting the inner circumference of the cylinder and is inserted into the roller; and a guide portion that extends from an axial end of the body portion in a direction crossing the direction the vane slides out, and that is slidably inserted into a guide groove formed on at least one of the first and second bearings to restrain the vane from sliding out of the roller toward the inner circumference of the cylinder in at least some part of the circumference of the cylinder. By this, the mechanical friction loss in the vane may be reduced.
