摘要： A scroll type fluid machine can suppress an increase of inclining vibrations of an Oldham ring with easier adjustments. A stationary scroll (1) and a swivel scroll (2), in a pair, are engaged with each other, and the swivel scroll (2) is driven to make revolutional motions, while being prevented from rotating, via an Oldham ring (18) disposed between an end plate (6) of the swivel scroll (2) and a frame (10). A distance between the end plate (6) of the swivel scroll (2) and the frame (10) is s and a thickness of a ring portion (19) of the Oldham ring (18) is t, A gap .delta., formed as (s-t) and a radius r of said ring portion (19) of the Oldham ring (18) is set so that .delta./r is 0.01 or less. Thus, by only the ring portion (19) of the Oldham ring (18) being adjusted in its thickness, an increase of inclining vibrations of an Oldham ring (18) can be suppressed.

摘要： A high pressure chamber in a casing communicates at the bottom thereof with a liquid retainer. A communication pipe is connected at one end thereof to the upper end of the liquid retainer and connected at the other end thereof to an intake pipe. A gas container and first and second solenoid valves are provided in the communication pipe. When the first solenoid valve is closed and the second solenoid valve (37) is opened, the gas container communicates with the intake pipe to reduce the pressure in the gas container. Thereafter, when the first solenoid valve is opened and the second solenoid valve (37) is closed, the gas container communicates with the liquid retainer to reduce the pressure in the liquid retainer. Then, the pressure of lubricant oil in the liquid retainer is lowered to gasify a refrigerant dissolving in the lubricant oil. As a result, lubrication malfunction caused due to lowering of the viscosity of the lubricant oil by dissolution of the refrigerant therein is avoided and the reliability of the hermetic compressor is enhanced.

摘要： A scroll type fluid machine has a pair of mutually engaged scrolls, one being made of an aluminum material, and the other being made hard. A wear amount of an engaging tip seal and end plate is reduced, and the growth of wear of both elements is equalized. Tip seals (47, 48) are provided at the tips of wraps (12, 16) of the pair of scrolls (10, 14) and are made of a composite plastic material composed of a polyphenylene sulfide as a base material and a carbon fiber, and other materials as filler. The carbon fiber composition rate of the tip seal material of the scroll (10) made of an aluminum material is made higher than the carbon fiber composition rate of the tip seal material of the other scroll (14) made of an aluminum material having a surface treatment or of a ferrous metal or of a ferrous metal having a surface treatment. Thereby the wear amount of each engaging tip seal (47, 48) and end plate (11, 15) is reduced, and simultaneously the growth of wear of both elements is equalized.

摘要： An inexpensive, efficient pump which can supply lubricating oil uses the revolving motion of an orbiting scroll 2. The pump is so constructed that a piston supported by a fixing member 1 is fitted in a cylinder chamber 102 formed in the inner surface of the end plate 21 of an orbiting scroll 2 which revolves while sliding on the fixing member, by which a pump chamber 104 is defined between them. The piston 101 is extended or retracted depending on the revolving motion of orbiting scroll 2, the volume of the pump chamber 104 is increased or decreased, and a fluid suction port 105 and a fluid discharge port 106 are connected to the pump chamber 104 at predetermined time intervals to supply the fluid.

摘要： A hermetic compressor includes a casing, a compression mechanism in the casing, a container member and a pressure reduction device. The casing includes a high pressure chamber, an intake pipe and a discharge pipe. The high pressure chamber contains lubricant oil that is supplied to the compression mechanism. The container member is a separate body from and communicates with a bottom part of the high pressure chamber so as to allow the lubricant oil to flow to and from the container member. The pressure reduction device sucks gas refrigerant in the container member and sends it to the intake pipe for reducing an inside pressure of the container member. The pressure reduction device is in fluid communication with the intake pipe at a location between the outlet of the evaporator and an inlet of compression mechanism. A refrigerator includes the hermetic compressor.

摘要： The present invention provides a scroll-type compressor that can supply sufficient lubricating oil without the occurrence of seizure of bearing for an orbiting scroll. In this scroll-type compressor, an annular boss 23 extends downward from the orbiting scroll, and an eccentric pin 53 of a rotating shaft 5 fits into the boss 23 via a bearing 73 and an eccentric bush 54. A gap 58 is provided between the eccentric pin 53 and the eccentric bush 54, and an oil supply path 57 is provided between the eccentric bush 54 and the bearing 73. The lubricating oil flows out of an oil supply hole 52 formed in a rotating shaft 5 and the eccentric pin 53, being supplied to the bearing 73, etc. via the oil supply path 57. In order to sufficiently supply the lubricating oil to the oil supply path 57, a portion 54f extending in an arcuate shape from the upper end face of the eccentric bush 54 forms a protrusion extending upward from the other flat portion 54d. The protrusion 54f may be formed in an annular shape along the inner peripheral surface of the eccentric bush 54, or a flat plate member 59 may be provided to close the gap 58 from the downside without providing the protrusion 54f.
