    摘要： A scroll-type compressor including stationary and orbiting scrolls housed in a shell. A first frame, also housed in the shell, receives a portion of the orbiting scroll. The stationary scroll is fixed to the first frame, and a second frame is further mounted in the shell. A balancer chamber is formed between the first and second frames. A main shaft having a balancer is housed in the balancer chamber rotatably. The main shaft includes an enlarged diameter portion on one end of the shaft which is attached to the orbiting scroll and a small diameter portion on the end of the shaft which is attached to the orbiting scroll and extending between the first frame and the second frame for driving the orbiting scroll. A first bearing is disposed between the main shaft in the first frame for supporting the main shaft at a position between the orbiting scroll end of the shaft. A second bearing is disposed between the main shaft and the second frame for supporting the main shaft at a position proximate opposite the end of the shaft. The main shaft has an axial oil passage that extends from a bottom portion that is in contact with an oil pan at the bottom of the shell to an eccentric hole in the top of the shaft that is adapted to receive the orbiting scroll shaft. Upon rotation of the shaft, oil is pumped up to the eccentric hole. An Oldham coupler at the top of the main shaft and motor mounting legs have oil return holes and passages that assure proper lubrication of the compressor.

    摘要： A scroll-type compressor including stationary and orbiting scrolls housed in a shell. A first frame, also housed in the shell, receives a portion of the orbiting scroll. The stationary scroll is fixed to the first frame, and a second frame is further mounted in the shell. A balancer chamber is formed between the first and second frames. A main shaft having a balancer is housed in the balancer chamber rotatably. The main shaft includes an enlarged diameter portion on one end of the shaft which is attached to the orbiting scroll and a small diameter portion on the end of the shaft which is attached to the orbiting scroll and extending between the first frame and the second frame for driving the orbiting scroll. A first bearing is disposed between the main shaft in the first frame for supporting the main shaft at a position between the orbiting scroll end of the shaft. A second bearing is disposed between the main shaft and the second frame for supporting the main shaft at a position proximate opposite the end of the shaft.The main shaft has an eccentric hole at the upper enlarged diameter portion thereof that can receive the shaft of the orbiting scroll. The main shaft has an oil passage connecting the lower end of the shaft, that is dipped into an oil pan, to the upper end of the shaft at the eccentric hole. The passage is structured to suck oil from the oil pan to the eccentric hole during rotation of the shaft. The eccentric hole has oil holes and passages that permit lubrication to flow to the appropriate bearings.

    摘要： A scroll-type compressor is disclosed which has a novel thrust bearing for supporting an orbiting scroll. The thrust bearing is annular and is supported by a bearing support frame which has a plurality of oil return holes formed therein. The diameter of the thrust bearing is smaller than the diameter of the orbiting scroll and of an Oldham coupling which guides the orbiting scroll. The thrust bearing has a plurality of oil passageways for lubricating oil formed therein whose inner ends open onto the central hole and whose outer ends communicate with the oil return holes and do not extend to the outer periphery of the bearing. The oil passageways are always covered by the orbiting scroll. In one form of the invention, the oil passageways are in the form of grooves formed in the upper surface of the bearing and through holes which communicate between the outer ends of the grooves and the oil return holes. In another form of the invention, the oil passageways are slits formed through the depth of the bearing. In another form of the invention, the oil passageways are a combination of slits formed through the depth of the bearing, through holes which communicate with the oil return holes, and grooves formed in the upper surface of the bearing which extend between the slits and the through holes.

    摘要： A scroll compressor is provided with a main shaft to drive an orbiting scroll whereby fluid in a compression chamber which is formed by combining a stationary scroll with the orbiting scroll is compressed and then is discharged from the scroll compressor. To prevent a refrigerant gas in an eccetric recess formed in the main shaft from mixing with a lubricating oil, a conduit is formed in the main shaft to communicate the eccentric recess with a space between the lower part of the orbiting scroll and the upper part of the main shaft.

    摘要： In a scroll type compressor, the shaft of a driven scroll is rotatably supported in a sealing container so that the axis of rotation of the driven scroll shaft is deviated from the axis of rotation of a driving scroll; the wrap plates of the driving and driven scrolls are mutually combined with each other so that the parts of the side surface of the wrap plates come in contact with each other to form a compression chamber; and the driven scroll is directly driven by the driving scroll in synchronism therewith, whereby the function of compression of a fluid is obtainable during the movement of the compression chamber toward the centers of the driving and driven scrolls.
