Abstract
Fuel injection pump, characterized comprises a cam, mobile pumping cores that move relative to the cam to move the contour of the cam to pumping strokes in sequence, a first source of fluid under pressure in correlation with the speed of the engine with which it is associated, a forward piston connected to the cam to adjust its relative angular position in order to control the synchronization of the pumping strokes; a first hydraulic chamber at one end of the advancing piston connected to the first fluid source for moving the advancing piston so as to advance the synchronization in response to the higher engine speed; a thrust spring that pushes the advancing piston in the opposite direction to the first fluid source; a second movable piston at the other end of the advancing piston; a second source of fluid under pressure in correlation with the operating conditions of the engine other than the speed; a second hydraulic chamber at the end of the second piston connected to the fluid source, and a stop to limit the movement of the second piston in the direction of synchronization delay, the second piston engaging the end of the advancing piston opposite the first chamber hydraulic when a predetermined amount of advance in synchronization is reached.
