    Abstract: Disclosed is a compressor. A lubrication surface, which has the same curvature as an inner circumferential surface curvature of a cylinder and which has a predetermined circumference length, is formed on an outer circumferential surface of a roller contacting an inner circumferential surface of the cylinder. With such a configuration, since the outer circumferential surface of the roller contacting the inner circumferential surface of the cylinder come in surface-contact with each other, an oil film is formed between the roller and the cylinder with a wide area. This can reduce a frictional loss.

    Abstract: A turbo compressor is disclosed. The turbo compressor has an assembly-type rotating shaft where a permanent magnet is inserted into a connecting sleeve, a first locking projection formed on either an inner periphery of the connecting sleeve or an outer periphery of the permanent magnet facing the inner periphery of the connecting sleeve, and a first locking groove formed on the other. Thus, the permanent magnet constituting a rotor may be easily coupled into the rotating shaft, and the permanent may be effectively prevented from slipping. Moreover, a magnet embedded in the rotating shaft may be securely fixed so that it is held in a position where it is assembled, thus providing an advantage in concentrically aligning the magnet.

    Abstract: A motor-operated compressor is provided that may include an orbiting scroll and a rear housing supporting a rear surface of the orbiting scroll. The rear housing may be provided with a discharge space communicating with a discharge port of the orbiting scroll formed at a central portion of a surface facing the orbiting scroll, an oil separation space formed at one side of the discharge space to communicate with the discharge space, and an oil storage space formed at an edge portion of the surface facing the orbiting scroll. An oil return passage may be provided between the oil separation space and the oil storage space, so as to guide oil separated in the oil separation space to the oil storage space. Accordingly, a space for storing oil separated from a discharged refrigerant may be sufficiently secured while allowing the rear housing defining the oil storage space to be easily fabricated.

    Abstract: A scroll compressor includes a communication hole formed to penetrate from a side surface of the non-orbiting scroll adjacent to a discharge side to a thrust bearing surface between the non-orbiting scroll and an orbiting scroll and a decompression member having a radial sectional area smaller than that of the communication hole and inserted into the communication hole. A refrigerant discharged to the discharge space is introduced to the suction space through the passage between the communication hole and the decompression member, thereby preventing a high vacuum state of the compression chamber, and a refrigerant passing through the communication hole is decompressed during a normal operation to restrain leakage of the refrigerant to the thrust bearing surface between the non-orbiting scroll and the orbiting scroll, thus increasing compression efficiency.
