    摘要： In a method of manufacturing a hollow rack shaft, an approximately rectangular plate having a wide rack tooth portion, is bent lengthwise into a gutter-like cross section to provide: at the central portion, a flat bottom portion on which rack teeth are formed later and a pair of mutually facing leg portions, and, in the vicinity of both ends, a semicircular bottom portion and a pair of mutually facing leg portions. The mutually facing leg portions at the central portion have a larger clearance than the clearance of the mutually facing leg portions in the vicinity of both ends. The rack teeth are then formed on the flat bottom portion through the plastic flow of the flat bottom portion and a part of material of the pair of leg portions of this flat bottom portion. The gutter-shaped plate, on which the rack teeth have been formed, is then formed into a tube having a hollow inner surface, by bending the plate and butt joining the edge portions.

    摘要： A lobed rotor-type pump has a drive shaft, a pump housing, an eccentric rotor journal, a rotor, three working-fluid chambers, intake and discharge ports, and a communication passage. The pump housing has a circumferentially-extending peri-trochoidal curved surface in its inner periphery. The eccentric rotor journal is fixedly connected to the drive shaft. The rotor is slideably fitted to the eccentric rotor journal. The rotor has three lobes equi-distantly spaced circumferentially around its outer periphery so that the rotor rotates eccentrically while keeping the lobes in sliding contact with the peri-trochoidal curved surface. The three working-fluid chambers, which are defined between respective three lobes and the peri-trochoidal curved surface, rotate in synchronism with the rotor. The intake and discharge ports are provided in the housing to input low-pressure incompressible fluid and to output high-pressure fluid. The communication passage is formed in the housing for communicating a first working-fluid chamber, decreasing in volume during the compression stage, and a second working-fluid chamber, increasing in volume during the expansion stage, to permit flow of incompressible fluid from the first chamber to the second chamber.

    摘要： A scroll type compressor including mutually mating stationary and movable scrolls for producing compression. A circumferentially outer part of the movable scroll portion has a flat end surface and a chamferred surface. The chamferred surface tapers outwardly at an angle relative to the flat end surface greater than an allowable tilt angle of the movable scroll. A circumferentially inner part of the scroll portion includes a flat end surface only which has a groove to receive a tip seal, the tip seal having a height greater than a depth of the groove. The circumferentially outer part has an identical outer diameter to that of the base plate portion, and the base plate portion and the scroll portion are simultaneously machined.

    摘要： A movable scroll element for a scroll type compressor is produced by a combination of a mold casting process and a machining process. The mold casting process produces a cast product having an end-plate forming portion, a spiral-member-forming portion and a projecting portion for forming a drive power receiving portion. The cast product has an entire outer faces covered with black scale, and the machining process machines the end-plate-forming portion, a spiral member forming portion, the projecting portion by cutting. Nevertheless, at least an outer circumference of the drive power receiving portion, i.e., a boss portion of the movable scroll element is covered with an outermost layer consisting of black scale. Thus, a sufficient mechanical strength of the movable scroll element is obtained even if the wall thickness of the drive power receiving portion, i.e., the boss portion of the movable scroll element, is reduced.

    摘要翻译： 用于涡旋式压缩机的动涡旋件通过模具铸造工艺和机加工的组合来生产。 模具铸造工艺生产具有端板形成部分，螺旋部件形成部分和用于形成驱动力接收部分的突出部分的铸造产品。 铸造产品具有覆盖有黑色刻度的整个外表面，并且机加工过程对端板形成部分进行加工，螺旋形成部分形成部分通过切割加工突出部分。 然而，驱动力接收部分的至少外圆周，即动涡旋件的凸起部分被最外层覆盖，最外层由黑色鳞片构成。 因此，即使驱动力接收部分的壁厚，即动涡旋件的凸起部分的壁厚减小，也可获得动动涡旋件的足够的机械强度。
