Abstract

Electric starter for internal combustion engine comprising: an electric motor (M) combined with means (R, L) for driving the internal combustion engine and an electronic filter (10) that is arranged on a power circuit (3) of the electric motor (M) that is suitable for at least reducing the electromagnetic disturbance caused by the operation of the electric motor (M). The electronic filter (10) is placed inside a cover (11, 30) of the starter.

Claims

1. Electric starter for an internal combustion engine, comprising:

an electric motor (M) associated with means (R, L) for driving the internal combustion engine, comprising a positive terminal and a negative terminal;

an electronic filter (10) comprising a positive terminal which is connected electrically to the positive terminal of the motor (M), and is designed at least to attenuate the magnetic disturbances generated by the functioning of the electric motor (M), wherein the electronic filter(10) is placed inside a cover (11, 30) of the starter.

2. Starter according to claim 1, characterized in that it comprises:

a launcher (L) which is mobile in rotation around itself, and is mobile in axial translation between a position of rest and a position of driving of the internal combustion engine;

means for rotation of the launcher by the electric motor (M);

an electromagnetic switch (C) which is designed firstly to control the power of the electric motor (M), and secondly to control the displacement of the launcher (L) between its position of rest and its drive position, the switch comprising an output terminal which is connected to the positive terminal of the filter and to the positive terminal of the motor (M);

at least one cover (11, 30) which partly covers at least the electric motor (M) and/or the electromagnetic switch (C);

and in that the electronic filter (10) is covered by the cover of the electric motor (M) and/or of the electric switch (C).

3. Starter according to claim 2, characterized in that the cover covers at least partly the electric motor (M) and/or the electromagnetic switch (C).

4. Starter according to claim 2, characterized in that it comprises a first cover (11) which covers at least partly the electromagnetic switch (C) and a second cover (30) which covers at least partly the electric motor (M).

5. Starter according to claim 4, characterized in that the first cover (11) covers the electronic filter (10).

6. Starter according to claim 4, characterized in that the second cover (30) covers the electronic filter (10).

7. Starter according to claim 1, characterized in that the cover (11, 30) comprises means for immobilizing the electronic filter (10).

8. Starter according to claim 7, characterized in that the electronic filter (10) is pressed against a resiliently deformable element (20) for elimination of play.

9. Starter according to claim 1, characterized in that the electronic filter (10) comprises connectors (17) which are crimped onto the lugs of the electronic components which constitute the filter.

10. Starter according to claim 2, characterized in that the electronic filter (10) comprises connectors (17) which are crimped onto the lugs of the electronic components which constitute the filter.

11. Starter according to claim 3, characterized in that the electronic filter (10) comprises connectors (17) which are crimped onto the lugs of the electronic components which constitute the filter.

12. Starter according to claim 4, characterized in that the electronic filter (10) comprises connectors (17) which are crimped onto the lugs of the electronic components which constitute the filter.

13. Starter according to claim 5, characterized in that the electronic filter (10) comprises connectors (17) which are crimped onto the lugs of the electronic components which constitute the filter.

14. Starter according to claim 6, characterized in that the electronic filter (10) comprises connectors (17) which are crimped onto the lugs of the electronic components which constitute the filter.

15. Starter according to claim 7, characterized in that the electronic filter (10) comprises connectors (17) which are crimped onto the lugs of the electronic components which constitute the filter.

16. Starter according to claim 8, characterized in that the electronic filter (10) comprises connectors (17) which are crimped onto the lugs of the electronic components which constitute the filter.

17. Starter according to claim 2, characterized in that the cover (11, 30) comprises means for immobilizing the electronic filter (10).

18. Starter according to claim 3, characterized in that the cover (11, 30) comprises means for immobilizing the electronic filter (10).

19. Starter according to claim 4, characterized in that the cover (11, 30) comprises means for immobilizing the electronic filter (10).

20. Starter according to claim 5, characterized in that the cover (11, 30) comprises means for immobilizing the electronic filter (10).

21. Starter according to claim 6, characterized in that the cover (11, 30) comprises means for immobilizing the electronic filter (10).
