摘要： In a revolution type compressor using a balance weight for balancing a rotating mass, the effect of oil churn reduction is enhanced, and compressor input is reduced. 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： The inside of a sealed container (50) of a horizontal scroll compressor is partitioned by a partition plate (80) into a space in which a compressor mechanism section and an electric motor are contained and into a discharge space (84) in which a discharge pipe (52) and an oil supply pump (70) are contained. An upper communication path (85) and a path guide member (81) are provided in the upper part of the partition plate, and a refrigerant gas passes through the upper communication path (85). The path guide member is located below the discharge pipe (52), is extended to a position near a side surface of the sealed container, and has a path area greater than the path area of the discharge pipe. The construction causes the refrigerant gas to collide with the side surface of the sealed container, promoting separation of oil, and even if the oil is re-dispersed by a gas flow, the construction reduces flow directly leading to the discharge pipe.

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.

摘要： Helium enclosed compressor. A compressor and a motor section with stator having coil ends and a rotor, are housed within an enclosed vessel partitioned into discharge and motor chambers by a frame. The compressor section has a stationary scroll having a spiral wrap standing upright at a disk-like panel and an orbiting scroll having a spiral wrap standing upright at a disk-like panel, made to mesh with each other while their wraps face the inside. The orbiting scroll sucks helium gas from a suction port of an outer peripheral portion of the stationary scroll, and discharges helium gas into the discharge chamber from a discharge port of a central portion of the stationary scroll. An inverter controls a number of rotations of the motor section, wherein a plurality of varnish-treated layers which becomes insulating films is formed on the surface of a coil which constitutes the coil ends.

摘要： In the hermetically sealed scroll compressor, an injection pipe for injecting a fluid to a compression chamber is connected to an injecting port of a fixed scroll. The injecting port includes a first injecting port which is provided in the vicinity of a fixed scroll inner curve and injects the fluid to an orbiting outer compression chamber, and a second injecting port 22b which is provided in the vicinity of a fixed scroll outer curve and injects the fluid to a orbiting inner compression chamber 8b. The second injecting port is placed in parallel in a radius direction with respect to the first injecting port and is placed so that an orbiting scroll wrap does not practically communicate with the orbiting outer compression chamber in the state in which the orbiting scroll wrap is in contact with the outer side of a fixed scroll wrap.
