ABSTRACT:
The mechanism comprises a rectilinearly movable roller guide which at its upper end can be coupled to the plunger of the fuel pump and in the lower end of which an arm is journalled by means of a pivot pin. The arm supports a follower roller which is held in contact with an actuating cam on the rotating control shaft of the engine. To the arm there is secured a pin engaging in a vertical guideway which can be moved horizontally so as to pivot the arm between two end positions each corresponding to one direction of rotation of the engine. Each end position is defined by the mutual engagement, under the influence of the force acting on the follower roller, between two abutment surfaces provided on the arm and the roller guide, respectively.
