Patent ID: 8258639

Claim:
A starting device for an internal combustion engine, comprising: a stator comprising an inductor coil, the inductor coil comprising a plurality of windings electrically connected in parallel; a rotor associated with the stator and having an axis of rotation; a starter element rotatable by the rotor and moveable along the axis of rotation of the rotor; and a contactor provided to supply power, in a prerotation first phase, only to some of the windings of the inductor coil and, in a full-speed second phase, following the first phase, to all of the windings of the inductor coil; the contactor having a longitudinal axis and comprising first and second electrical contact elements provided to supply power to the electric motor so as to enable the electric motor to operate in succession in the prerotation first phase and the full-speed second phase; each of the first and second contact elements moveable along the longitudinal axis between an open state and a closed state; the first contact element movable relative to the second electrical contact element; the contactor comprising: a movable support engaging the first electrical contact element; a control rod engaging the second electrical contact element; and a movable assembly provided to push the movable support along the longitudinal axis so as to move the first electrical contact element from the open state to the closed state and to push the control rod along the longitudinal axis so as to move the second electrical contact element from the open state to the closed state; the control rod movable relative to the movable support; the number of the windings activated in the second phase being equal to or greater than twice the number of the windings activated in the first phase; the movable assembly provided to move the starter element by a pivoting fork.
