摘要： A scroll compressor contains a suction chamber and a compression chamber formed between the orbiting scroll and stationary scroll; and the rear surface of the orbiting scroll includes a back pressure chamber to apply a pressing force for pressing the stationary scroll to the orbiting scroll by the pressure higher than the pressure in the suction chamber. The stationary scroll contains the communication paths 200, 201 to connect the suction chamber or the compression chamber and the back pressure chamber; and a back pressure control means for opening and closing the communication paths by way of the pressure differential along the communication paths. The inlet communication path 200 that extends from the back pressure control means to the back pressure chamber includes at least two or more path cross-sectional areas. The cross-sectional area of an inlet communication path 301 on the back pressure chamber side of this inlet communication path is formed larger than the cross-sectional area of an inlet communication path 302 on the back pressure control means side. Moreover, the opening surface area of the back pressure chamber side of the communication path 301 is configured so as to be constantly equal to or smaller than the cross-sectional area of the communication path 302 so that a section of the back pressure chamber side opening 300 of the communication path 301 is constantly blocked by the base plate of the orbiting scroll, and in this way a highly efficient and highly reliable scroll compressor is achieved.

A balance weight fixed to a drive shaft between a rotor of an electric motor 4 and a compression mechanism includes a weight portion in a substantially semicircular column shape for balancing a rotating mass, a cover portion which is substantially semi-cylindrical and has an opening in the vicinity of a top and bottom at an opposite side in a radial direction from the weight portion, and a hollow space surrounded by the weight portion and the cover portion. Further, a space for discharging oil is provided between the balance weight and the rotor. By the structure, reduction in oil churn, and reduction in input of the compressor are realized, and the compressor with less power consumption is obtained.

摘要： A scroll compressor is provided in which the amount of lubricant oil supply is appropriately controlled over a low to high rotational frequency range of the scroll compressor. The scroll compressor has an oil supply unit and an oil supply passage. The oil supply unit includes a small hole with a diameter not exceeding a seal ring width of the sealing part and a groove which are formed on the end plate of the boss portion on the back side of the orbiting scroll. As the orbiting scroll orbitally moves, oil in the high pressure hydraulic chamber pools in the small hole to be discharged, across the seal ring, into the back pressure chamber. The oil supply passage communicates between the high pressure hydraulic chamber and the back pressure chamber.
