- a micro-solenoid 240 controls the movement of a ring 941 which is placed between the terminal 250 input and 251 output terminal.
- the plunger moves the contact plate 931 in translation to said terminals 250, 251.
- Said contact plate 931 comprises a degree of freedom in translation parallel to the direction of displacement of the plunger, and return means 932 tending to push the contact plate towards the terminals 251, 252.
- the power supply of the mircro-solenoid 240 of the auxiliary actuator prevents the contact plate 931 from being in contact with the terminals 250 and 251 through the ring 941.
- return means 942 causes the ring 941 to be withdrawn and the contact plate 931 return means 931 push said plate into contact with the terminals.
- the ring 941 is not in contact with the plate 931 when it is in contact with the input terminal.
- the ring 1 141 in the activated position prevents said contact plate 831 from being in contact with the terminals 251 and 250.
- the main actuator pushes, through the plunger 130 and the plate 931, the ring 1 141 in the deactivated position which then allows the contact of the plate 931 with the two terminals 251 and 250.
- the micro solenoid 240 preferably comprises a return spring 1 142 of the ring 1 141 to the activated position to ensure that it prevents contact between the plate 931 with one or both terminals 250, 251 and on the other hand attenuate the vibrations at rest.
- the ring in the deactivated position, the ring is in contact with the plate.
- the ring comprises a portion preferably metal to be movable by the micro-solenoid but the end of the ring 841 in contact with the contact plate 831 is electrically insulated.
- Figure 1 1A when the micro-solenoid 240 is energized, its action is added to that of the spring 1 142 and pushes the ring January 141 which spreads the plate 931 contact terminals.
- Figure 1 1 B when the micro-solenoid 240 is no longer supplied, the action of the plunger 130 pushes the ring 1 141 by compressing the spring 1 142.
- the embodiments shown in FIG. 10 and FIG. 11, have the advantage that, in the absence of a power supply, the action of the springs 1042, 1 142 acting on the auxiliary actuator 1041, 1042 tends to open the contact between terminals.
- the auxiliary actuator is, by default, in the configuration adapted to the sequence of steps, so as to further reduce the restart time.
- the description above and the exemplary embodiments show that the invention Achieves the objectives in particular, it reduces the restart time of an internal combustion engine by pre-engaging the starter gear while said combustion engine is still rotating.
