PURPOSE:To make machining easier and enable ports and passages to be easily formed by constructing an injector body and a pressure feed cylinder in a separate body respectively. CONSTITUTION:In an injector body 6 is formed a fitting hole 11, into which a pressure feed cylinder 7 is fitted. An injection cylinder 8 is pressure welded to the bottom face of the pressure feed cylinder 7, and a nozzle holder 9 is brought in contact with pressure with the bottom face of the injection cylinder 8. And these pressure feed cylinder 7, injection cylinder 8, and nozzle holder 9 are combined in an integrated form by means of a holder nut 10 which is screwed onto the injector body 6. And, a pressure feed plunger 15 is slidably fitted in the pressure feed cylinder 7, forming a pressure pump chamber 16. |
