The invention relates to a device for controlling a starter for a heat engine that is equipped with an electric motor having a field coil with several windings and an armature winding, both of which are mounted in series, comprising a power contact which is equipped with terminals, one of said terminals being connected to the positive terminal (+Bat) of a battery and the other terminal being connected to the field coil having several windings. The inventive device comprises first means which, in a first phase upon closure of the power contact, activate part of the windings of the field coil and second delayed-action means which, in a second phase during which the power contact is always closed, activate at least a large number of the windings of the coil. The invention is intended for the heat engine starter of a vehicle.

Device for controlling a heat engine starter, such as that of a motor vehicle, and starter comprising one such device

Motor vehicle starter comprising a starter head provided with a pinion (), a driver () and a coupling device with a conical clutch for coupling the pinion to the driver (), in which the conical clutch comprises a first frustoconical friction surface () fixed to the pinion and a second frustoconical friction surface (') with a shape complementary to the first surface () and fixed to the driver and in which the coupling device comprises on the one hand a hollow-shaped coupling piece having. a bottom extended by an annular skirt directed axially towards one of the elements consisting of pinion and driver and on the other hand axially acting elastic means () bearing on a first stop fixed to the coupling piece for acting on a second stop fixed to one of the elements consisting of pinion and driver. The elastic means comprise axially deformable tongues () and extend circumferentially.

A starter head for the starter of an internal combustion engine includes a motor shaft, on which a starter pinion is mounted for axial sliding movement. A free wheel and a driving sleeve are secured on the starter pinion by means of a securing shroud. The starter pinion has a bore over the whole of its length, with the motor shaft being displaceable within this bore. The starter has a device for limiting the axial throw of the starter head. The throw limiting device comprises a stop ring cooperating with a further ring fixed on the free end of the engine shaft within the bore of the pinion. The stop ring is fitted in a semicylindrical groove formed in the bore.
