Fuel injector with strainer |
摘要 |
A fuel injector including an injector casing having a fuel inlet at a side portion thereof; a valve housing having a fuel injection hole at a front end thereof and having a guide hole at an axial central portion thereof, the guide hole being communicated with the fuel inlet; a valve reciprocably accommodated in the guide hole, the valve being adjusted to close the fuel injection hole when advancing and open the fuel injection hole when retracting; a valve driving device for driving the valve to advance and retract the valve; and a fuel strainer mounted on an outer circumference of the injector casing, the strainer comprising a synthetic resin frame having annular portions at front and rear ends thereof and a metal ring connected to at least one of the front and rear end portions of the frame by insert molding of synthetic resin, the metal ring being press-fitted with the injector casing. With this construction, the generation of a gap due to the creep of resin between the injector casing and the strainer can be prevented to thereby prevent entry of a foreign matter into the injector.
