摘要： When a rotary shaft of a scroll type compressor rotates and a movable scroll of the compressor makes an orbital movement around the axis of a rotary shaft by way of an eccentric shaft, refrigerant gas is supplied to compression chambers between a fixed scroll and the movable scroll. A first bearing rotatably supports the rotary shaft. A second bearing is provided between the movable scroll and the eccentric shaft to permit relative movement therebetween. A balance weight attached to the movable scroll dynamically balances the movable scroll during its rotation. A crank chamber accommodates the balance weight. A suction port is so provided in the housing as to communicate with the crank chamber, and permits the refrigerant gas to be supplied into the housing. A passage is formed in the balance weight, the eccentric shaft and the rotary shaft to supply the refrigerant gas into a first gap between the first bearing and the rotary shaft and a second gap between the second bearing and the movable scroll.

摘要： A scroll compressor having a stationary scroll member and a rotary scroll member. The compressor is provided with a mechanism for obtaining an orbital movement of the rotary scroll member while preventing a rotation thereof about its own axis. The mechanism has a stationary and a rotary ring arranged in parallel and spaced from each other. These rings form a plurality of circumferential spaced facing pairs of circular holes. The mechanism also has shoes arranged in the respective holes and balls arranged between the shoes in the facing pair of holes. The shoes can maintain a parallel location with respect to the corresponding holes, since the shoes are movable relative to the ball. A sealtight contact of the rotary scroll member with the stationary scroll member is realized over a prolonged period.

摘要： A heat-insulating mechanism in a compressor which introduces refrigerant gas from a suction pressure region to a compression chamber and discharges the refrigerant gas from the compression chamber to a discharge pressure region has a circular passage, a communication passage, a cylindrical member and a passage heat-insulating member. The circular passage, which is a portion of the suction pressure region, has a circular cross-section, and is in communication with an external refrigerant circuit. The communication passage, which is a portion of the suction pressure region, intersects the circular passage for connection therewith, and is communicable with the compression chamber. The cylindrical member is fitted into the circular passage. The passage heat-insulating member made of an insulating material covers at least a portion of a passage wall surface which forms the communication passage. Rotation of the cylindrical member is prevented by engaging the passage heat-insulating member with the cylindrical member.

摘要： Lubricating oil feeding mechanism has an oil-collecting recess and an oil-supplying groove formed on the wall of the housing. The oil-collecting recess connects a gap defined between the through hole and the bolt to the oil-supplying groove, the gap being in the upper position with respect to a sliding part to be lubricated in the housing in an operating state of the mounted compressor. The oil-collecting recess extends from the gap in the circumferential direction of the drive shaft, and the oil-supplying groove upwardly extends toward the oil-collecting recess. The oil-supplying groove is arranged so as to guide lubricating oil to the sliding part. Lubricating oil adhered on the bolt can be collected to the oil-collecting recess via the gap, and is fed to the sliding part through the oil-supplying groove. Therefore, a large amount of lubricating oil in a swash plate chamber can be utilized to lubricate the sliding part.

摘要： A refrigerant compressor includes a compression mechanism, a discharge passage, and an oil separator. The compression mechanism compresses a refrigerant gas containing a lubricant oil. The refrigerant gas that has been compressed by the compression mechanism flows through the discharge passage. The oil separator is arranged in the discharge passage and separates the lubricant oil from the refrigerant gas flowing in the discharge passage. The oil separator has a rotator that causes the refrigerant gas to flow around the axis of the rotator and a circumferential wall that encompasses the rotator and extends along the axis of the rotator. The rotator and the circumferential wall define a separation zone in between. The lubricant oil is separated from the refrigerant gas by the flow of the refrigerant gas around the rotator in the separation zone. The circumferential wall has an oil outlet that allows the separated lubricant oil to flow to the exterior of the oil separator. The oil separator has an inlet port that allows the refrigerant gas to flow into the separation zone and an outlet port that allows the refrigerant gas to flow out of the separation zone. The rotator is arranged between the inlet port and the outlet port. The inlet port and the outlet port are arranged so that an inlet direction of the refrigerant gas flowing through the inlet port is substantially parallel with an outlet direction of the refrigerant gas flowing through the outlet port.
