Abstract
A compressor is provided that eliminates sliding contacts between a cylinder and a roller to minimize mixing of lubricating oil into a refrigerant. The compressor includes a hermetic container that stores the lubricating oil at a lower portion thereof; a stator mounted within the hermetic container; a cylinder type rotor that rotates within the stator by a rotating electromagnetic field of the stator and defines a compression chamber therein; a roller that rotates and compresses the refrigerant by a rotational force transferred from the rotor; a rotational shaft integrally formed with the roller; a vane that divides the compression chamber into suction and compression regions and transfers the rotational force to the roller; and oil feed passages provided in the rotational shaft and the roller to feed the lubricating oil to areas where two or more members are slidingly engaged with one another within the compression chamber.
