摘要： Mass-produced fuel pumps having a stable pump efficiency comprising a circumferential groove 20 is formed within a pump body 15 and the groove 20 is divided into a first region having a constant cross-sectional area L, a second region having a cross sectional area that gradually becomes smaller toward the downstream side, and a third region having a constant cross-sectional area M. A suction hole 22 is formed within the pump body 15 and is inclined toward the rotational direction of the impeller. The suction hole 22 is communicated with the groove 20 in the first region. Even if the inclination angle of the suction hole 22 varies among mass-produced fuel pumps, the cross-sectional area L of the groove 20 is constant at the location where the suction hole 22 is communicated with the groove 20. Therefore, variations in the amount of fuel sucked into the fuel pump can be reduced. Accordingly, pump efficiency of the mass-produced fuel pumps can be stabilized.

摘要： A method of driving an engine valve-driving electromagnetic valve, wherein a permanent magnet is provided in a movable element of the electromagnetic valve, and springs are omitted, and wherein repulsion and attraction electric currents are varied according to the engine speed, thereby reducing the electric power consumption. The permanent magnet is magnetized in the axial direction. When the repulsion current is passed through one exciting coil, the attraction current is passed through the other exciting coil, thereby moving an engine valve to an open position. When the attraction current is passed through the one exciting coil, the repulsion current is passed through the other exciting coil, thereby moving the engine valve to a closed position. In the low-engine speed region, the current value is smaller and the energization time is longer than in the high-engine speed region.
