摘要： In a fuel pump having a high pump efficiency, an annular portion is formed on an outer periphery of an impeller to let one- and opposite-side blade grooves be independent of each other. Then, various improvements are made such as tilting front and rear wall surfaces of the blade grooves in a predetermined direction, forming one- and opposite-side blade grooves in a zigzag fashion, forming a guide surface in a communicating passage of a pump housing, and forming communicating holes in an impeller.

摘要： Two-inner gears are overlapped with each other through a partition wall and are eccentrically arranged at an inner peripheral side of an outer gear, and eccentric directions of both the inner gears are shifted from each other by 180° to the opposite side. By this, loads in an outer diameter direction due to a rise in fuel pressure affect one outer gear from the two inner gears oppositely to each other by 180°, so that an eccentric load is not generated, and sliding resistance of the outer gear to a cylindrical casing becomes small. Further, the number of teeth of the outer gear is made odd, and the number of teeth of the inner gears is made even.
摘要翻译：两内齿轮通过分隔壁彼此重叠，并且偏心地布置在外齿轮的内周侧，并且两个内齿轮的偏心方向彼此偏移180°到相对侧。由此，由于燃料压力上升，在外径方向上的负载使两个内齿轮的一个外齿轮相互相对旋转180°，从而不会产生偏心负载，外齿轮的滑动阻力圆柱形壳体变小。此外，外齿轮的齿数变得奇数，并且使内齿轮的齿数均匀。

摘要： A commutator having even number (2n) of commutator segments and n segment pairs, each pair consisting of two commutator segments positioned symmetrically with respect to a commutator center, is mounted on a rotor of an electric rotary machine. The commutator segments are electrically insulated from one another, while the commutator segments in each pair are electrically connected to each other. A metallic base plate and a carbon segment plate are molded together with resin, and then the commutator segments are separated into individual segments. Connecting portions for electrically connecting the commutator segments in each pair are formed integrally with the metallic base plate at positions depressed from a surface of the metallic base plate, so that the connecting portions are not cut in the process of separating the segment plate into individual commutator segments.

摘要： When differential pressure between fuel flowing into a fuel control valve and fuel flowing out of the valve reaches a predetermined value, the biasing force of a compressed coil spring is countered and a shaft in the valve moves to the fuel upstream side so that a valve member is seated to terminate communication between the fuel inlet passage and the fuel outlet passage. This maintains fuel pressure at the fuel inlet passage and at the fuel outlet passage at different levels so that the fuel supply system maintains a high fuel pressure in the fuel rail to suppress fuel vapor generation during engine stoppage while also yet still providing an appropriate fuel injection pressure during rapid deceleration of the vehicle.
摘要翻译：当流入燃料控制阀的燃料和流出阀的燃料之间的压差达到预定值时，压缩螺旋弹簧的偏置力被反向，并且阀中的轴移动到燃料上游侧，使得阀构件被安置以终止燃料入口通道和燃料出口通道之间的连通。这维持燃料入口通道和燃料出口通道处于不同水平的燃料压力，使得燃料供应系统在燃料轨道中保持高燃料压力，以抑制发动机停止期间的燃料蒸气产生，同时仍然提供适当的燃料喷射车辆快速减速时的压力。

摘要： A Westco type fuel pump includes an impeller (32) which has a plurality of vane grooves (322) and a plurality of vane plates (323) provided alternately along its outer periphery. Each vane groove (322) is constituted by groove portions (322a, 322b) formed in both sides of the impeller (32), respectively, with a partition wall (321) provided between the groove portions (322a, 322b). The partition wall has an outer peripheral surface (3210) located radially inside an outer peripheral surface (3230) of each vane plate (323) and has a predetermined thickness in an axial direction of the impeller. As the impeller (32) rotates, two vortex flows of fuel are generated along bottom surfaces (3221, 3222) of the groove portions (322a, 322b) and then smoothly merge together at a position outside the outer peripheral surface (3210) of the partition wall, thereby reducing a flow dead zone (96) in a pump flow passage (33). When the impeller (32) is molded by using molds, deformation of the molded impeller is prevented due to the thickness of the outer peripheral surface (3210). Of the surfaces of the impeller (32), therefore, the surfaces of each vane groove remain as they are after the molding, while both sides of the impeller (32) and the outer peripheral surfaces (3230) of the vane plates (323) are ground. Thus, the impeller (32) able to surely achieve a high level of pump performance can be easily provided by resin molding.
摘要翻译：一种Westco型燃料泵包括具有沿其外周交替设置的多个叶片槽322和多个叶片板323的叶轮32。每个叶片槽322由形成在叶轮32的两侧的槽部322a，322b构成，分隔壁321设置在槽部322a，322b之间）。隔壁具有位于各叶片板323的外周面3230的径向内侧的外周面3210，并且在叶轮的轴向上具有规定的厚度。当叶轮（32）旋转时，沿凹槽部分（322a，322b）的底表面（3221,3222）产生两个燃料涡流，然后在外部周边表面（3210）外侧的位置处平滑地合并在一起从而减少泵流道（33）中的流动死区（96）。当通过模具模制叶轮（32）时，由于外周面（3210）的厚度，防止了模制叶轮的变形。因此，在叶轮（32）的表面中，每个叶片槽的表面在模制之后保持原样，而叶轮（32）的两侧和叶片板（323）的外周面（3230）是地面的因此，可以容易地通过树脂成型提供能够确实获得高水平的泵性能的叶轮（32）。

摘要： In a rotary electric machine including a stator core and a stator winding received in slots of the stator core, a cooling medium baffling device is provided which comprises a cooling medium baffle plate fixed to the inner peripheral edge of one end of the stator core by mounting bolts protruding axially from the end of the stator core, wherein the circumferential position of each of the mounting bolts is displaced from the circumferential position defining the boundary between the different modes of phase currents flowing through the coils constituting the stator winding, thereby effectively eliminating generation of excessive heat due to excessive eddy current losses occurring locally at the end of the stator core.

摘要： An electric rotary machine is provided with a stator having a stator core of laminated iron plates with a given lamination thickness in an axial direction of the machine and a stator winding wound around the core and a rotor rotatably disposed inside the stator, having a rotor core and a rotor winding. The axial length of the stator core is selected with respect to that of the rotor core in such a way that, when the rotor is thermally extended, the end of the rotor core never extends beyond the end of the stator core. With such a constructional arrangement, there is eliminated an excessive temperature rise at the ends of the stator core, and prevented an insulation deterioration of the stator winding and the burning of the stator core.
