ABSTRACT:
A fuel injection pump which has a pump piston disposed in a pump housing and guided in the pump housing. A drive tappet connected to the pump piston is movable by means of a mechanical drive element in a longitudinal direction of the pump cylinder counter to the force of a restoring spring. A guide sleeve surrounds a tappet insert and is guided in a reciprocating direction of the pump piston in a guide tube disposed on the pump housing and surrounded by the restoring spring. The guide sleeve includes a loss prevention device for the drive tappet and pump piston. The guide sleeve has an inwardly oriented collar with a bearing surface upon which a U-shaped disk rests and the disk presses against an outer collar provided on the pump piston. This disk keeps the pump piston in contact with the tappet insert of the drive tappet. A lateral opening is provided in the wall of the guide sleeve, above the bearing surface of the U-shaped disk, through which the U-shaped disk can be introduced.
