    • An electric fuel pump for pumping a liquid fuel from a tank to an engine. The pump device has a regenerative pump section and an electric motor section for driving the regenerative pump section. The regenerative pump section includes a pump casing having a first inner surface and a second inner surface axially opposing to and spaced from each other to define therebetween a pump chamber, a shaft adapted to be rotatingly driven by the electric motor section and an impeller accommodated by the pump chamber and mounted on the shaft for rotation therewith but axially movably relatively thereto. The impeller has one axial end surface opposing to the first inner surface with a first gap formed therebetween, and the other axial end surface opposing to the second inner surface of the pump casing with a second gap formed therebetween. The first inner surface and the second inner surface of the pump casing has axial thrust generating surfaces which are so shaped as to gradually decrease the first and the second gaps towards the downstream sides as viewed in the direction of flow of fuel introduced into these gaps. In consequence, axial thrust forces are generated by wedging action of the fuel introduced into the gaps so that the impeller is kept out of contact with the inner surfaces of the pump casing during operation of the pump device.
    • 一种用于将液体燃料从罐泵送到发动机的电动燃料泵。 泵装置具有再生泵部和驱动再生泵部的电动机部。 再生泵部分包括具有第一内表面和第二内表面的泵壳体,所述第一内表面和第二内表面轴向地相对并彼此间隔开,以在其间限定泵室,适于由电动机部分旋转地驱动的轴和由 泵室并安装在轴上以与之旋转,但可相对于其轴向移动。 叶轮具有与第一内表面相对的一个轴向端面,其间形成有第一间隙,另一轴向端面与泵壳的第二内表面相对,并在其间形成有第二间隙。 泵壳体的第一内表面和第二内表面具有轴向推力产生表面,其形状为当从引入到这些间隙中的燃料的流动方向观察时,朝向下游侧逐渐减小第一和第二间隙。 因此,通过引入到间隙中的燃料的楔入作用产生轴向推力,使得在泵装置的操作期间叶轮与泵壳的内表面保持脱离接触。

    • A regenerative pump has a pump housing and a disc-like impeller mounted in the housing so as to be rotated by a motor. The impeller is provided with circumferential rows of radial vane grooves formed in the opposite end faces of the impeller adjacent to the outer periphery thereof. The rows of grooves are surrounded by a circumferential fluid passage which is formed between the impeller and the pump housing and communicated with suction and discharge ports formed in the pump housing and open to the circumferential fluid passage adjacent to the outer peripheral edges of respective end faces of the impeller. Each of the vane grooves has a bottom face which is arcuate as viewed in a radial section of the impeller. The suction port is substantially tangential to the bottom face of each vane groove in the adjacent end face of the impeller at the junction between the groove bottom face and the end face of the impeller.
    • 再生泵具有泵壳体和安装在壳体中的盘状叶轮,以便通过马达旋转。 叶轮设置有形成在叶轮的与其外周边相邻的相对端面中的圆周排的径向叶片槽。 各排的槽被形成在叶轮和泵壳体之间的周向流体通道包围,并且与形成在泵壳体中的吸入口和排出口连通,并且与相邻端面的外周边缘相邻的周向流体通道开口 的叶轮。 每个叶片槽具有在叶轮的径向截面中观察到的弓形的底面。 在槽底面和叶轮的端面之间的接合处,吸入口基本上与叶轮的相邻端面中的叶片槽的底面相切。

    • A power transmission device for vehicles comprises: a housing rotatably supporting a crank shaft of an engine of the vehicle; a first shaft rotatably supported inside the housing to be coaxial with the crank shaft; a clutch unit having a drive member arranged inside the housing and coupled to the crank shaft, and a driven member fixed to the first shaft; a second shaft rotatably supported inside the housing to be parallel to the first shaft. The device has also infinite variable transmission including a drive pulley consisting of a fixed sheave and an axially movable sheave mounted on the first shaft, a driven pulley consisting of a fixed pulley and an axially movable sheave mounted on the second shaft, and a V belt which is placed the driving and driven pulleys through V grooves defined by the fixed and axially movable sheaves of the driving and driven pulleys. Hydraulic piston-cylinder assemblies are fixed to the axially movable sheaves and to the associated first and second shafts so that they move the axially movable sheaves towards and away from the associated fixed sheaves. A rotary pump is disposed at the housing has a rotary element operatively coupled to the crank shaft for rotation therewith to generate a hydraulic pressure upon rotation, and which supplies the hydraulic pressure to the hydraulic piston-cylinder assemblies.
