ABSTRACT:
A hub 1 integral with the injection pump to include a housing 2 driven in rotation, surrounding hub 1 and including two rollers 4, 5 placed parallel to the axis of the housing at a distance from this axis. An eccentric governor weight 15 is mounted on hub 1 to be able to move in one direction under the action of the centrifugal force. Two advance control pistons 8, 9 with axis orthogonal to the axes of the hub are mounted in the hub, each to be able to slide in a recessed bore and each equipped with a lateral support ramp 10, 11 able to work with one of the rollers 4, 5 to cause an angular offset between hub 1 and housing 2. One of the pistons 8 acts in the other direction on governor weight 15 by a spring 18. A hydraulic circuit goes through the hub and has a distributor with controlled relief 20 adjusting the pressure acting on pistons 8, 9 as a function of the position of governor weight 15. An additional piston 32 modifies the position of balance of governor weight 15 as a function of the pressure prevailing in the hydraulic circuit. A correction device acting as a function of the temperature of the hydraulic fluid can also be provided.
