ABSTRACT:
A pump nozzle for a diesel engine, in which an injection pump element including a pump piston driven by a cam-shaft and a bushing is combined with an injection nozzle to a unit provide be associated with a motor cylinder. The pump piston is surrounded by an axially shiftable control sleeve controlling the begin of fuel injection in dependence on its axial position. A regulating member is guided on the pump element body for rotation relative to the control sleeve in dependence on an operating parameter of the motor. The control sleeve or the regulating member has a race which has, as seen in a top plan view, a circular shape and including with a normal plane extending in normal relation to the pump piston at least partially a pitch angle. A guide element which is rigidly connected with the respective other part (i.e. the regulating member or the control sleeve cooperates with this race. By the cooperation of this guide element with the race, the control sleeve is, during the relative rotation, lifted or lowered and the beginning of fuel injection is controlled. The race may also have in mutually succeeding sections angles of inclination of different size and/or of different orientation.
