<p>The regulating device described comprises an element (51) which senses the rotational speed of the injection pump shaft (1) and controls the pump rack (6). The movement of said rack is limited mechanically (61, 62, 63, 64, 65, 67), in a known manner, in function of the position of the accelerator pedal (67). The degree of movement of the rack (6) is therefore proportional to the distance travelled by the accelerator pedal (67). The essence of the invention is a d.c. generator the rotor (2) of which is mounted on the shaft (1) of the injection pump. The stator (4) of the generator is torsionally mounted on the pump against the force of a spring (41) and is linked by a mechanical transmission (43, 45) to a forked stop (46) which prevents further movement. The element (51) which senses the rotational speed of the pump shaft (1) regulates the excitation voltage of the stator (4) by means of a control unit (5).</p> |
