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 scroll compressor is provided that may include a communication hole that penetrates from a side surface of a 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 a radial sectional area of the communication hole and inserted into the communication hole. A refrigerant discharged to a discharge space may be introduced to a suction space through the passage between the communication hole and the decompression member, thereby preventing a high vacuum state of a compression chamber, and a refrigerant passing through the communication hole may be 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.

Abstract: A turbo compressor is disclosed. The turbo compressor may have an assembly-type rotational shaft where a permanent magnet is inserted into a connecting sleeve, at least one 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 at least one first locking groove formed on the other. Thus, the permanent magnet constituting a rotor may be easily coupled into the rotational shaft, and the permanent may be effectively prevented from slipping. Moreover, a magnet embedded in the rotational 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 includes a drive motor and a rotary shaft coupled to the rotor. A first scroll disposed on one side of the drive motor is eccentrically coupled to and orbitally moved by the rotary shaft. A second scroll faces the first scroll and is coupled to the first scroll to form a compression chamber. A hollow portion is formed inside the rotary shaft along an axial direction, and an eccentric portion having a rotary shaft side discharge hole extends from the rotary shaft center to a rotary shaft outer circumferential surface. The first scroll includes a rotary shaft coupling portion surrounding an outer circumferential surface of the eccentric portion. The rotary shaft coupling portion is provided with a first scroll side discharge hole formed at a position periodically facing the rotary shaft side discharge hole to discharge compressed fluid to the rotary shaft side discharge hole.
