    摘要： Disclosed is a roller for use in a rotary compressor, which roller comprising a sintered body consisting essentially of 0.5-2.0% by weight of C, 1.0-5.0% by weight of Cu, 1.2-3.0% by weight of Mo and a balance of Fe and unavoidable impurities. In the sintered alloy, hard particles of Fe-Mo alloy are dispersed in one of pearlitic and tempering martensitic matrix, and sintered pores of the sintered body is sealed with tri-iron tetroxide. Resultant sintered body has high wear resistance and scuffing resistance capable of being used as an inverter type compressor.

    摘要： A moving vane type compressor has a cylinder which is made of a sintered material having a density of 6.6 to 7.6 and a composition consisting essentially of 0.6 to 0.8% of carbon, 1 to 2% of copper and the balance substantially iron. The cylinder is encased by a hermetic casing therebetween a high pressure chamber into which a refrigerant compressed by the compressor is discharged. Lubricating oil separated from the discharged refrigerant within the high pressure chamber and the lubricating oil suspended in the form of a mist by the refrigerant attach to the outer peripheral surface of the wall of the cylinder made of the sintered material. The oil attaching to the outer peripheral surface of the cylinder is forced by the refrigerant pressure acting thereon into the pores of the sintered material such as to block these pores, thus preventing the compressed gas in the cylinder from leaking outside through the pores.

    摘要： A stator for a helical gear device is formed from multiple rigid disks and support rings bonded to the disks. Each disk forms part of a profile consisting of radially equally spaced or opened lobes which interact with the convex portions of rotor lobes. The disks are arranged into a desired helical configuration and bonded to one another to form a disk stack defining a helically convoluted elongated chamber therein. The support rings are fixed concentrically against respective end disks of the disk stack. The rings are sized with an inside diameter substantially equal to the major diameter of the central aperture defined by the radially extending lobes of the rigid disks. As a rotor rotates and nutates inside the helically convoluted elongated chamber of the stator, it is supported at both ends of the disk stack by the support rings touching the tips of the rotor lobes. Thus the full force of the rotor's operational inertia is not borne by the disks alone, thereby increasing their life.

    摘要翻译： 用于斜齿轮装置的定子由多个刚性盘和结合到盘的支撑环形成。 每个盘形成轮廓的一部分，该轮廓包括与转子叶片的凸起部分相互作用的径向等间距或开放的叶片。 盘被布置成所需的螺旋构造并且彼此结合以形成在其中限定螺旋卷积的细长室的盘叠。 支撑环与磁盘堆叠的相应的端盘同心地固定。 这些环的尺寸大小与内径基本上等于由刚性盘的径向延伸的叶片限定的中心孔的长度的直径。 当转子旋转并且在定子的螺旋卷积的细长室内旋转时，其通过接触转子叶片的尖端的支撑环被支撑在盘堆叠的两端。 因此，转子的操作惯性的全部力量不是单独由磁盘承担的，从而增加其寿命。
