摘要： PURPOSE:To stabilize the oil supply by maximizing the fluid resistance of an oil groove of a last thrust bearing in an oil flow path thereby making the pressure loss between the outlet of a pump and the outlet of the thrust bearing higher than the pressure to be boosted by means of a final stage pump means. CONSTITUTION:Lubricant 17 flows through an oil cap 16-an eccentric oil supply hole-a rolling section bearing oil groove 10a-an oil groove 6d-an oil groove 32a. The length and the number of the oil grooves 32a in the thrust bearing 32 are set such that the pressure loss of the lubricant flowing through the oil groove 32a is higher than the pressure to be boosted by a final stage pump means 23. Consequently, when the lubricant flows through the bearing section, negative pressure does not occur thereby intrusion of gas is prevented.

摘要： PURPOSE:To improve compression efficiency through improving the sealing performance of the side part of a spiral projection by forming an antiwear material layer on the top of an elastic material layer which is formed on either of the opposed side-wall faces of both spiral projections. CONSTITUTION:To both side-wall 1d, 2d faces of the spiral projections 1a, 2a of a fixing and a driven scroll 1, 2, are stuck rubber-like elastic material layers 6, to the surfaces of which an antiwear material layers 7 composed of tetrafluoroethylene resin and the like are stuck. By this constitution, when the side-walls 1d, 2d come into contact with each other, the elastic deformation of the rubber-like elastic material layers 6 prevents the leakage of the fluid and at the same time the antiwear material layer 7 prevents the occurrence of wear, and therefore the sealing performance is maintained over a long period, thus enabling the improvement of compression efficiency.

摘要： PURPOSE:To improve the sealing performance between the scroll projections of drive and driven scrolls by rotating the driven shaft of the driven scroll around a movable bearing support thereby varying the distance between the centers of the shafts of both scrolls. CONSTITUTION:A driven scroll 2 is born by a movable bearing support through a thrust bearing 13 and the driven shaft 5 thereof is born in a central through- hole of said support 12 through a bearing 14. A portion of the outer circumference of said support 12 is coupled through a bearing 37 to a supporting shaft 36 while a portion of the outer circumference at the opposite side from said bearing 37 is coupled to a fluid pressure cylinder 40. When said support 12 is rotated around the supporting shaft 36 by the pressure of fluid in said cylinder 40, the distance between the centers of the driven shaft 5 of the driven scroll 2 and the drive shaft 4 of the drive scroll is varied thereby the sealing gap between the scroll projections 1a, 2a of said scrolls 1, 2 is varied.

摘要： PURPOSE:To secure lubrication to a bearing and prevent a seizure or rubbing thereof, by forming an oil holder for holding lubricant at the bearing or at the shaft to rotatably support a swinging scroll. CONSTITUTION:At a main driving shaft 8 with a bearing 11 for rotably supporting a swinging scroll, is formed an oil flow passage for linking the bearing 11 to an oil sump 10. This oil passage is composed to be an oil holder 9 to holding oil by a capillarity, and suppolies oil securely to the bearing 11 even when it takes time to feed oil to be bearing at the starting of the drive. Therefore, a seizure or a rubbing at the bearing 11 can be prevented.

摘要： PURPOSE:To permit the easy restoration of the effect the transmittivity change of an information recording medium and to improve the durability and S/N of a disk by using a transparent semiconductor for the recording medium, using radiation for recording and using laser light for reproducing and erasing. CONSTITUTION:The transparent semiconductor by a GaP circular wafer 15 is used for the recording medium and the writing of the information is executed by irradiating a charged particle beam 14 from a radiation generator 13 on the wafer 15 and blackening the crystal to change the transmittivity of the light. The reading out of the information is executed by passing the laser light 11 from a laser device 3 through an objective lens 5, irradiating the same on the wafer 15 and detecting the transmitted laser light 121 with a detector 4. The power of the laser light 11 is increased and is condensed by a lens 5 to locally increase the temp. of the wafer 15 and to annihilate and erase the blackened part in the case of erasing. The restoration of the effect by the transmittivity change of the wafer 15 is made easy and the durability and S/N of the device are improved.

摘要： PURPOSE:To prevent a key from being adapted to a key groove, in a condition deflecting to one side, while seizure and/or abnormal wearing from being generated, by providing the key and the key groove, engaged with said key, in an Oldham's coupling to be offset in a load direction receiving rotating torque of a swivel scroll on its own axis. CONSTITUTION:In order to move keys 13b and key grooves 2d, 8a in an Oldham' s coupling to be parallelly slided with no contact deflecting to one side, the keys 13b, formed on upper and bottom surfaces of an Oldham's ring 13a in the Oldham's coupling, are offset by a value P in a load direction receiving rotating torque M of a swivel scroll 2 on its own axis with respect to straight lines 30, 31 crossing at right angles with each other passing through the center of the Oldham's ring 13a. In this way, a compressor, removing shaky looseness between the keys 13b and the key grooves 2d, 8a, moves the whole surface of the key 13b to be slided on groove wall surfaces of the key grooves 2d, 8a, even if the swivel scroll 2 generates rotating torque M on its own axis.

摘要： PURPOSE:To prevent a swiveling scroll shaft from generating abnormal wearing and/or seizure, by performing high-frequency quenching after a hollow hole of the swiveling scroll shaft is drilled to a position inside a swiveling scroll bed plate. CONSTITUTION:A hollow hole 19, provided in a swiveling scroll shaft 2b, is drilled to a position inside a bed plate 2a of the swiveling scroll shaft 2b. Here the swiveling scroll shaft 2b, if it performs high-frequency quenching, enables sufficient hardness to be obtained because a thermal capacity of the swiveling scroll shaft 2b comes to be in a sufficiently small level.

摘要： PURPOSE:To store oil inside a lubrication hole in advance at all times as well as to make a speedy feed of lubricating oil to a bearing part performable in time of restarting, by installing a check valve consisting of a ball or the like in the midway of the lubrication hole being open to the central part of a crankshaft so as to cause oil to flow back downward. CONSTITUTION:During operation, oil is sucked out of an opening part 15a installed in a crankshaft 14, then goes up inside a lubrication hole 5 being open to the central part of a shaft 4 and fed to each bearing. At the point midway in the lubrication hole 15, there is provided with a check valve consisting of a ball 26a so as not to cause the oil to flow back downward but since this ball 26a is lightly moved upward in particular, the oil is able to flow without almost all resistance there. On the other hand, in time of stopping a compressor, oil inside the lubrication hole 15 is prevented from its back flow as the hole 15 is blocked up by the ball 26a and therefore the oil is always stored inside the lubrication hole 15. With this constitution, in time of restarting, lubrication to each bearing part gets started in a short time and even in starting under condition that bearing load is large enough, sufficient bearing performance can be brought into full play.

摘要： PURPOSE:To obtain a seal device with a simple structure, a low cost, high compression efficiency, and high reliability by pressing by pressure a seal member inserted into a groove on a spiral side plate of a scroll by means of the elastic deformation of a pressure fluid. CONSTITUTION:A tip seal 5 is made of an elastic material mold, and it is constituted in a cross section formed by the upper end surface 5b brought into contact by pressure with the end plate surface of a stationary scroll and a recessed portion 5a where the U-shaped rear side of the surface 5e on an opposite side is opened, and a gap 8 is formed between the rear surface 5e and the bottom surface 6c of the groove 6. When the gas is compressed, the high-pressure gas flows into the gap through a notch 7, thus energizing the tip seal 5 upward in the axial direction toward the end plate 1b of the stationary scroll 1 through the U-shaped recessed portion 5a surface, and the upper end surface 5b of the tip seal 5 is slidably brought into contact with the lower surface of the end plate 1b, and the axial sealing is performed.
