Abstract

The roller rotatably located on a roller bolt runs on the path of a camshaft cam. The roller bolt is releasably fixed to the roller tappet. Above the pump piston in the bottom dead centre position is arranged a pump work chamber connected by holes with a fuel chamber and by at least one injection valve with nozzle with the combustion chamber of the engine. The roller bolt (20) is crossways displaceable to the axis of the camshaft (19). The holes in the roller bolt for fixing the bolt to the tappet (16) are formed as long holes running crossways to the longitudinal axis of the bolt. The contact surfaces (24) between the roller bolt and the roller tappet are of the positive engagement type.
