A starter battery voltage step-up device (LPF) intended to prevent a drop in the battery voltage (Vbat) produced by a current surge in a power circuit of the starter when the starter is powered on. The device comprises a casing of magnetic material (C, YO, CM, CM'), a primary winding circuit (W) intended to be inserted in series in the power circuit, and a short-circuited secondary winding circuit (W), in which the primary winding circuit (W) and/or the secondary winding circuit (W) comprises a winding formed by at least one flat conductor () wound on edge. The invention also relates to the corresponding combination () of a starter and a voltage step-up device.

The motor vehicle starter ( ) has a casing ( ) in which there is arranged an electric motor ( ) which rotates a coaxial starter head ( ) with the interposing of an epicyclic gearbox ( ) including a ring gear ( ) made of rigid material (M ) which is housed at least partially in a cavity ( ) in the casing and which has an internally toothed cylindrical annular skirt ( ) closed at its front axial end by a radially oriented transverse wall ( ) with a hole at its centre ( ) for the output shaft ( ) of the gearbox to pass; the ring gear ( ) has pins (P) moulded from a flexible material (M ), notably elastomer material, which are interposed between the ring gear ( ) and complementary portions ( ) of the cavity ( ) of the casing ( ) in order to immobilise the ring gear ( ) rotationally with respect to the casing ( ) and provide a function of torsion damping between these two components ( ).

The invention relates to a starter motor switch in which there are arranged a stationary magnetic core and a winding at the center of which a plunger moves to act on a rod, a portion of which carries a contact intended to establish contact between two terminals, of the type in which the stationary core delimits a chamber and a chamber and of the type in which the stationary core has a cavity in which a portion of the rod is accommodated, wherein it comprises a sealing partition comprising a transverse plate resting against the front face of the stationary core, which is extended by a rim which interacts in a sealed manner with the cover, and comprising a central part, the shape of which complements that of the central cavity with which it interacts in a sealed manner.
