ABSTRACT:
A timing advance variator for a fuel injection pump, the reciprocal movement of which is obtained by means of a transverse arm fixed to the drive shaft acting on the piston and in contact, by means of rollers, with a cam ring disposed in the pump casing, characterized by the fact that the cam ring is connected by a worm helical gear device the pin of which is constrained axially to the injection pump casing, which pin can be rotated by driving means for the movement of the cam ring.
