摘要： A vane-type compressor includes a rotor shaft that includes rotating shaft portions and a rotor portion, which are integrated with one another. A lower end of the rotating shaft is disposed in an oil reservoir. The vane-type compressor also includes vane aligners disposed at both end portions of vanes, and recess portions, which are respectively formed in a frame and a cylinder head so as to be concentric with an inner circumferential surface of a cylinder. Outer circumferential surfaces of the vane aligners are slidably supported by the recess portions. In the rotor shaft, oil supply channels, which allow communication between the oil reservoir and the recess portions of the frame and the cylinder head, and an oil pump, which supplies refrigerating machine oil in the oil reservoir to the oil supply channels, are provided.

摘要： A refrigerant compressor that enhances compressor efficiency by both reducing an amplitude of pressure pulsations and reducing pressure losses in a discharge muffler space into which is discharged a refrigerant compressed at a compression unit. A low-stage discharge muffler space is formed in the shape of a ring around a drive shaft. In the low-stage discharge muffler space, a discharge port rear guide is provided in the proximity of a discharge port through which is discharged the refrigerant compressed by a low-stage compression unit. The discharge port rear guide is provided at a flow path in one direction out of two flow paths from the discharge port to a communication port in different directions around the drive shaft, and prevents the refrigerant from flowing in that direction, thereby causing the refrigerant to circulate in a forward direction in the ring-shaped discharge muffler space.

摘要： A refrigerant compressor includes: an electric motor including a stator and rotor inside a sealed vessel; a compressing mechanism driven by a crank shaft in the rotor; a lower portion oil pool storing in the sealed vessel lubricating oil that lubricates the compressing mechanism; an upper counterweight on an upper end of the rotor. Refrigerant gas compressed by the compressing mechanism is discharged inside the sealed vessel, passes through a gas channel formed on the electric motor, moves from a lower space to an upper space with respect to the electric motor, and is discharged outside the sealed vessel. An oil return flow channel is formed on the upper end of the rotor toward a lower end from a vicinity of a leading end portion of the upper counterweight in a direction of rotation, and oil expressed in a vicinity of the rotor is directed to the oil return flow channel.

摘要： A scroll compressor has an electric motor portion, a compression mechanism portion connected to the electric motor portion, and an oil sump for lubricating oil in a sealed container and compresses a refrigerant in the compression mechanism portion. A used refrigerant is a halogenated hydrocarbon or a hydrocarbon having a carbon double bond in the composition or is a mixture containing one of the same. A sliding surface of at least one of two components constituting a sliding portion having a relation of sliding to each other in a sealed container is structured in such a way that an iron metal or an aluminum metal is not directly exposed.

摘要： In a vane rotary compressor, a discharge valve on a discharge flow channel communicates an operating chamber in a compression element with a discharge hole. The discharge valve is pushed from an opening portion of a discharge valve groove to an outer circumferential surface of a roller by a high-pressure refrigerant when pressure in an operating chamber is lower than the pressure of the high-pressure refrigerant. The discharge valve is pushed back into the discharge valve groove by the refrigerant pressure in the operating chamber when the pressure in the operating chamber is higher than the pressure of the high-pressure refrigerant. The discharge flow channel is closed by the outer circumferential surface of the discharge valve pushed out from the opening portion of the discharge valve groove and the outer circumferential surface of the roller, and opens when the discharge valve is pushed back into the discharge valve groove.

摘要： An enclosed motor compressor of a two cylinder type in which a clearance between the eccentric portion of the second rotary shaft and the second sub bearing is set greater than a clearance between the eccentric portion of the first rotary shaft and the first main bearing, and also there is formed a clearance between the eccentric portion of the second rotary shaft and the second main bearing, so that, even when the second rotary shaft moves in the axial direction thereof, there is eliminated the possibility that the eccentric portion of the second rotary shaft can be in touch with the second main bearing and second sub bearing in the axial direction, thereby being able to reduce noise. Also, the pair of main bearings further include, on the side of the compression elements, assembling jig mounting portions to which the assembling jig can be mounted. Due to this, when assembling the main bearings, the accuracy with which the main bearings are made parallel to each other can be improved, and thus the performance and reliability of the compressor can be improved, thereby being able to reduce noise.
