ABSTRACT:
The pump
ozzle unit for a fuel injection system is disclosed which has a pump piston that is driven via a drive tappet and is rotatable by means of a regulating sleeve. The regulating sleeve, provided with a radially protruding control lever arm, is axially secured in its installed position by means of a guide bushing. The guide bushing includes a guide part for the drive tappet and a radially protruding flange, which is secured to the pump housing by at least one holder passing through an oblong slot on the flange of the guide bushing. A recess in the form of a circular segmented ring is cut out of the guide bushing for the passage therethrough of the control lever arm. By rotating the guide bushing within a range limited by the oblong slot a lateral limiting edge of the recess is adjustable into a position in which the pump piston, with the control lever arm resting on the limiting edge assumes a rotational position associated with a fixed supply quantity. As a result, no further additional or full-load stop device is necessary and mounting of the drive unit and pump assembly on the engine are facilitated.
