PURPOSE:To make it possible to set the position of a lever for a ring which rotates a valve opening pressure change-over cam, by means of a spline to adjust it to the attachment position of the lever, in a vortex chamber type Diesel-engine, by projecting the lever laterally. CONSTITUTION:A valve opening pressure change-over cam 103 is disposed in a nozzle body 120 while a ring 102 for rotating the cam is arranged on the outer periphery of the nozzle body, and the lever section 101b of a lever 101 for rotating the ring 102 through a spline 102c is laterally projected. With this arrangement, even if an injection nozzle is mounted in an engine while it is rotated with a fuel supply port 122 and a return passage 121B being directed in the axial direction, the pipe line therefor may be set up. Further, the position of the lever may be set by the spline 102c to be adjusted to its attaching position. Therefore, by shifting the lever position at which the valve opening pressure is changed over relative to the nozzle body 120, the maximum value of sum of torques may be lowered, thereby it is possible to aim at reducing the operating force of the lever. |
