摘要： A rotary pump for pumping compressible fluid comprising an eccentrically mounted rotor 20 and a stator 10. The stator 10 comprises a stator inner liner 80 that is free to rotate, driven directly or in response to rotation of the rotor 20 such that the relative velocity between the outer surface of the rotor 20 and the inner surface of the stator 10 is reduced. The vanes 40 are held at each end by sockets 90, 95 in the rotor 20 and stator 10. The vane 40 and socket 90, 95 coupling provides fluid sealing without liquid lubricant. Opposing solid lubricant and hard surfaces are used on contact surfaces between the elements.

摘要： Scroll compressors (1) may include a housing (2, 3) having an inlet port (3a) and an outlet port (3b). A drive scroll (10) may be rotatably disposed within the housing and may have a rotational axis. A driven scroll (20) may be rotatably disposed within the housing and may have a rotational axis. The driven scroll rotational axis preferably is offset with respect to the drive scroll rotational axis. Further, at least one compression chamber (30) is preferably defined between the drive scroll and the driven scroll. First bearings (14, 16, 16a) may rotatably support one of the drive scroll and the driven scroll in a straddle manner. A second bearing (24) may rotatably support the other of the drive scroll and the driven scroll in a cantilever manner. A transmission (31, 131, 231 and 331) or other device may be provided to rotate the driven scroll in synchronism with the drive scroll.

摘要： A rotating type machine including a first moving member having a first surface and a second member having a second surface slidably interfacing with the first surface. The first and second surfaces have relative movement therebetween, and one of the first and second members is supported by the other member through the interface of their respective first and second surfaces. At least one of the first and second surfaces is provided with at least one recess therein. A liquid lubricant is provided between the first and second surfaces, and the lubricant is received in the recess. Relative to the surface in which the recess is provided, the recess has a maximum depth which ranges between about 0.00125 and 0.0060 inches, and a surface area which ranges between about 1.767×10−4 and 1.963×10−3 square inches, whereby, during operation of the machine, a pressure spike is created in the lubricant above the recess, and first and second surfaces are hydrodynamically separated from each other by the pressure spike.

摘要： A scroll compressor has a unique oil supply port for supplying lubricant to both the seals and the Oldham coupling. The oil supply port is positioned at a location such that it will not likely result in undue amounts of lubricant being entrained into the refrigerant leading into the compression chambers. The present invention is thus an improvement over the prior art.

摘要： An anti-rotation device for a scroll compressor. The scroll compressor includes intermeshed and nested stationary and orbiting scroll elements which define at least one spiraling compression pocket therebetween and an orbital drive mechanism for driving the central axis of the orbiting scroll element about the central axis of the stationary scroll element. The anti-rotation device maintains the orbiting scroll element substantially non-rotational with respect to the stationary scroll element during its orbit thereabout and includes at least one anti-rotation bearing which includes a first bearing element mounted stationary with respect to the stationary scroll element, a second bearing element mounted on the orbiting scroll element and an offset crank member. The offset crank member has a first shaft portion rotatably engaging the first bearing element and a second shaft portion which is radially offset from the first shaft portion by a distance equal to the radius of orbit, is parallel thereto and rotatably engages the second bearing element. Preferably, the first and second bearing elements are rotational bearing components, the second shaft portion of the offset crank member non-rotatably engages, via a conically tapered fitting, a bushing member, which itself rotationally engages the second rotational bearing component, and at least three such anti-rotation bearings are disposed at equal angular displacements (e.g., 120°) about the central axis of the scroll compressor.

摘要： A scroll-type compressor includes a fixed first scroll member, an orbital second scroll member, and a ball coupling provided as a rotation preventing mechanism for the second scroll member. The ball coupling has a pair of plates integrally formed with ring-like ball rolling grooves and a plurality of balls disposed therebetween. The compressor comprises a driven crank mechanism creating a swing motion for producing an orbital movement of the second scroll member. The amount of variation of the swing angle due to the driven crank mechanism is set within a range predetermined in accordance with a diameter of a ring form of each of the ring-like ball rolling grooves. The variation of the orbital radius of the orbital movement of the second scroll member corresponding to the swing angle may be regulated within a most appropriate range, thereby preventing occurrence of problems in the rotation preventing mechanism with respect to abrasion, performance and durability.

摘要： In a scroll compressor, generation of excessive vibration attributable to a ferrous Oldham's ring is eliminated, the fatigue failure and the operation noise are prevented, and the reliability is improved. Only an Oldham's key under sliding motion is formed of a metallic bush formed of iron excellent in the reliability in slidability, and an annular part large in volume is manufactured of light metal such as aluminum, and assembled to reduce the weight. That is, the bush excellent in wear resistance is press-fitted and locked to a light Oldham's ring formed of aluminum alloy in which a projection is integrated with the annular part. Alternatively, both sides of the projection which are the sliding sides with key grooves may be formed in arc shape. In this construction, the scroll compressor is obtained, in which generation of the excessive vibration attributable to a conventional ferrous Oldham's ring is eliminated thereby, the fatigue failure and the operation noise attributable to the vibration are prevented, the reliability is high, and the fabricability is excellent.
