摘要： A fuel injection valve, having an injector pipe containing a needle valve therein, an electromagnetic coil for driving the needle valve and a yoke forming a magnetic circuit, intermittently injects fuel fed from the top of the injection valve to an internal combustion engine according to longitudinal movement of the needle valve. The injector pipe is made of a compound magnetic material and formed into a single piece by a drawing process, the single piece including two magnetic portions and a non-magnetic portion interposed between two magnetic portions. The non-magnetic portion intercepts magnetic flux flow between the magnetic portions. The electromagnetic coil is molded by resin together with other components, and the yoke is formed separately. The yoke is mounted on the molded coil from its lateral side, making an assembly including the coil and the yoke. The injector pipe is inserted into a bore formed in the coil, and then the yoke is connected to the injector pipe by welding. The yoke and the molded coil are designed so that they are automatically positioned at a right place when they are assembled. Thus, the fuel injection valve is easily assembled in a simple process and at a low cost.

摘要： In a fuel supply device for an engine, a clip is fitted in two grooves formed in a fuel injector through its pawls parallel with each other, and fitted with a convex portion formed on a fuel delivery pipe through its window portion. The clip is prevented from slipping out of the injector in an axial direction and the fuel delivery pipe. Even if a wire harness tends to slip out of an electric connector, a sealing member is stopped at a stopper plate of the clip to thereby prevent the wire harness from slipping out.

摘要： A fuel supply system is composed of a fuel rail, a fuel injection valve and a fuel filter. The fuel injection valve has an electromagnetic solenoid, a valve member, a valve guide member and a valve seat. A plurality of slanted fuel passages are formed in the surface of the valve guide to evacuate bubble from the fuel. The fuel rail is composed of a resinous upper case member and a resinous lower case member. The fuel injection valve is held between the upper and lower case members in the axial direction of the valve. An elastic sheet member is interposed between the upper case member and the fuel injection valve, and an elastic O-ring is disposed around the fuel injection valve to reduce stress applied to the fuel injection valve in installing the fuel rail to an engine.

摘要： A fuel injector has a chamber between a valve body and a plate in which a plurality of through holes are formed. The chamber has a diameter larger than that of an opening of the valve body. The through holes are opened at an outer chamber area shaded by the valve body are distanced from an outer wall of the chamber more than a diameter of the through hole. Fuel flowing along an inner inclined surface of the valve body turns to the through holes and flows into the through hole from all directions and collides with each other at inlets of the through hole. Therefore, injected fuel has a lot of turbulences and is finely atomized.
