PURPOSE: To enable the start of injection to be adjusted simply and correctly by connecting a control sleeve surrounding a piston with a separating sleeve, and allowing the separating sleeve to be shiftable in direction of inclination and parallel to a particular plane. CONSTITUTION: In a pump nozzle, an injection pump member formed by a piston 1 and a bushing 11 are connected with an injection nozzle 8, and the piston 1 is surrounded by a control sleeve 12. In this case, the control sleeve 12 is connected to a separating sleeve 17, and the separating sleeve 17 is axially shiftable along guide surfaces 11a, 11b of the bushing 11. Hook-like protrusions 21, 22 are arranged on the separating sleeve 17 at the side opposite to the injection nozzle 8. The hook-like protrusions 21, 22 are shiftable in direction of inclination and parallel to a plane perpendicular to the axis of the piston 1, which is the plane 23 extending in transverse relation to the axis. |
