Abstract: A compressor eliminates sliding contacts between a cylinder (132) and a roller (142) to minimize the mixing of lubricating oil into refrigerant, and is structured to evenly distributing lubricating oil over sliding contact portions of a compressor actuator by pumping the oil from the inside on an axis of rotation (141), the compressor comprising: a hermetic container (110) storing oil at a lower portion; a stator (120) mounted within the hermetic container (110); a cylinder type rotor (130) rotating within the stator (120) by a rotating electromagnetic field from the stator (120), with the rotor (130) defining a compression chamber inside; a roller (142) rotating within the compression chamber of the cylinder type rotor (130) by a rotational force transferred from the rotor (130), with the roller (142) compressing refrigerant during rotation; an axis of rotation (141) integrally formed with the roller (142) and extending in an axial direction; a vane (143) dividing the compression chamber into a suction region where refrigerant is sucked in and a compression region where the refrigerant is compressed/discharged from, with the vane (143) transferring the rotational force from the cylinder type rotor to the roller (142); and oil feed passages provided to the axis of rotation (141) and the roller (142), with the oil feed passage feeding oil that is pumped along the motion of the axis of rotation (141) to an area where two or more members are slid onto within the compression chamber.

Abstract: A scroll compressor according to the present disclosure includes a fixed scroll, an orbiting scroll forming first and compression chambers with the fixed scroll, first and second compression chamber oil supply holes formed through the orbiting scroll to communicate with the first compression chamber and the second compression chamber, respectively, wherein when a section in which the first compression chamber oil supply hole is opened toward the first compression chamber is a first crank angle range and a section in which the second compression chamber oil supply hole is opened toward the second compression chamber, a non-overlap range between the first crank angle range and the second crank angle range may be longer than an overlap range between the first crank angle range and the second crank angle range, so as to prevent communication between the first and second compression chambers, thereby suppressing leakage between the compression chambers.

Abstract: A scroll compressor according to the present disclosure may include a refrigerant suction pipe coupled to a discharge cover or a fixed scroll through a casing in a radial direction, a suction passage communicating the refrigerant suction pipe with a compression chamber, and a suction passage opening and closing valve disposed inside the suction passage to be slidable in an axial direction so as to selectively open or close the suction passage. Accordingly, when the compressor is stopped, oil or refrigerant in the casing can be blocked quickly so as not to flow back to the refrigerant suction pipe through a compression unit.
