ABSTRACT:
An injector includes a casing having a through-hole extending along the axis thereof from a front end surface thereof to a rear end surface thereof; a valve housing inserted in the through-hole through the front end surface and adapted for slidably guiding a valve; a fuel pipe inserted in the through-hole through the rear end surface; and a solenoid coil disposed in a space defined between the outer peripheral surface of the fuel pipe and the inner peripheral surface of the casing. The through-hole of the casing includes an enlarged-diameter portion opening to the rear end surface, an intermediate-diameter portion provided in front of the enlarged-diameter portion and a reduced-diameter portion provided in front of the intermediate-diameter portion. The fuel pipe is inserted at least to a position where it reaches the intermediate-diameter portion, a cylindrical block being fitted on a portion of the fuel pipe to be inserted in the casing. A sealing ring is disposed in a compressed manner in an annular space defined by a rear end surface of the reduced-diameter portion, an inner peripheral surface of the intermediate-diameter portion, a front end surface of the cylindrical block and an outer peripheral surface of the fuel pipe. The inside of the reduced-diameter portion is separated from the inside of the enlarged-diameter portion so as to prevent leakage of fuel.
