    摘要： A fuel injector (40) to inject fuel into a cylinder of an internal combustion engine when installed therein, the engine having a high-pressure fuel supply which delivers fuel to the injector (40) and a lowpressure fuel return which removes fuel from the injector. The injector (40) has an injector body (42) which defines an interior cavity (46), a movable needle valve (54) which cooperates with the interior body to define a variable-volume control chamber (50) and valve means for selectively permitting fluid communication between the control chamber (50) and (1) the high-pressure fuel supply (48); and (2) the low pressure fuel return (52). Such fluid communication permits controlled variation of the volume of the control chamber (50) which, in turn, varies the position of the needle valve (54) to selectively permit or prevent fluid communication between the high-pressure fuel supply (48) and the engine cylinder. The valve means for selectively permitting fluid communication is preferably force balanced by relatively low forces acting thereon.

    摘要： The purpose of the present invention is to provide a fuel injection device and diesel engine whereby it is possible to reduce the amount of fuel oil supplied to a combustion chamber when a valve is closed. A fuel injection device (10) is provided with a housing (14), a needle valve (26), a spool valve (44) provided to a distal end of the needle valve (26), and a vertical groove (23) formed in a different position from fuel injection holes (16a-16d) and communicated with a fuel supply path (24), a fuel oil introduction space (27) through which fuel oil passes being formed in the spool valve (44), the fuel oil introduction space (27) being communicated with the vertical groove (23) and the fuel oil introduction space (27) moving to a position of communication with the fuel injection holes (16a-16d) when the fuel supply passage (24) is open, and an external peripheral face of the spool valve (44) confronting the fuel injection holes (16a-16d) and the fuel oil introduction space (27) moving to a position of non-communication with the fuel injection holes (16a-16d) when the fuel supply path (24) is closed.
