Abstract
A starter comprises an electric motor which drives a rotor shaft, a drive shaft that can be rotationally coupled to the rotor shaft, and a pinion mounted on the drive shaft and movable in a translational movement between a rest position and an active position by a movement system. The starter comprises a coupling system that couples a rotary movement in one direction of rotation of the rotor shaft to the pinion. The coupling system moves from an uncoupled state into a coupled state and vice versa. In the coupled state, the rotor shaft is firmly attached to the pinion in the starting direction of rotation. In the uncoupled state, the pinion is disconnected from the rotor shaft in both directions of rotation. The starter further comprises a movement system for moving the pinion from the coupling system into the uncoupled state as it moves the pinion into active position.
