摘要： A return spring assembly for use in an engine intake throttle valve return device comprising a spring holder sleeve (17) including an inner and outer sleeves (18,20) placed over a throttle valve shaft (3) and connected at one end to each other so that the inner and outer sleeves (18,20) are spacedly and concentrically held. Inner and outer torsion coil springs (8,9) are supported on the inner and outer sleeves (18,20), respectively, and connected between an intake barrel (1) and the valve shaft (3) for urging the throttle valve (2) to its closed position. An eccentric radial flange (22) which may be circular, oval or polygonal is provided on the outer sleeve (20) for holding the outer torsion coil spring (9). The eccentric flange (22) extends continuously over the entire circumference of the outer sleeve (20) and has a maximum outer diametrical dimension substantially equal to the inner diameter of the outer torsion coil spring (9). The eccentric flange (22) is eccentric with respect to the outer sleeve (20) by an amount effective to prevent the outer coil spring (9) from being disclocated from the outer sleeve (20).

摘要： A fuel injection valve includes a valve seat which has a valve seat surface, an injection nozzle having an inclined axis center, and a conically-shaped tapered surface located between the valve seat surface and the injection nozzle; and a valve element for controlling fuel supply to the injection nozzle. One part of an opening of the injection nozzle is connected to the tapered surface; the other part of the opening is connected to the valve seat surface; and a relationship between an angle θ1 formed by the injection nozzle and the tapered surface at an area where the injection nozzle is connected to the tapered surface side, and an angle θ2 formed by the injection nozzle and the valve seat surface at an area where the injection nozzle is connected to the valve seat surface side is configured to be θ1≧θ2.
