Abstract
The lever (13) cooperates on the one hand with a rotatable part (12) and, on the other, is coupled with a to-and-fro movable adjusting member (14). The lever (13) consists of a housing (15) traversed by the rotatable part (12), of a piston-like spring plate (16) and of a return spring (19) clamped-in between housing (15) and sping plate (16). Spring plate (16) and rotatable part (12) form in the mutually cooperating area a torque-limiting driving device. The hollow space (25) underneath the spring plate (16) is adapted to be acted upon with oil pressure by bores (21, 22) in the rotatable part (12) which are controllably connected to a pressure oil source (24). The oil pressure displaces the spring plate (16) so that the driving device is disengaged. The lever (13) is then displaced by the spring (27) of the to-and-fro movable part into an end position independently of the position of the rotatable part (12) which corresponds to the zero delivery of the fuel injection pump (11).
