First Claim
Patent Images
1. An electric starter for an internal combustion engine, comprising:
- an electric motor (M) operatively connected to a driving device (R, L) for driving the internal combustion engine, comprising a positive terminal and a negative terminal;
an electronic filter (10) comprising a positive terminal connected electrically to the positive terminal of the electric motor (M), and configured to attenuate electromagnetic disturbances generated by rotation of the electric motor (M);
a launcher (L) a drive pinion gear rotatable around a longitudinal axis (X) and moveable in axial translation along the longitudinal axis (X) between a position of rest and a position of driving of the internal combustion engine;
a gear speed reducer for rotating the launcher by the electric motor (M); and
an electromagnetic switch (C) configured to control the power of the electric motor (M) and to control the displacement of the launcher (L) between the position of rest and the position of driving of the launcher (L), the electromagnetic switch (C) comprising an output terminal connected to the positive terminal of the filter and to the positive terminal of the motor (M);
the electronic filter (10) placed inside a cover (11, 30) of the starter;
the cover (11, 30) at least partly covering the electromagnetic switch (C); and
the electronic filter (10) covered by the cover of the electric switch (C).
