The invention relates mainly to a starter (11) for a motor vehicle combustion engine, comprising: an electric motor (15), a drive pinion (60), a pinion body (61) on which said drive pinion (60) is mounted, a drive shaft (12) able to transmit a torque derived from the electric motor (15) to the drive pinion (60) via the pinion body, the pinion body (61) being mounted with the ability to slide axially with respect to the said drive shaft (12), and in which, with there being a chamber (86) delimited notably by one end of the drive shaft (12) and one end of the pinion body (61) opposite the end of the drive shaft (12), the chamber (86) is vented via a through-opening (85) made in an annular wall of the drive shaft (12) or of the pinion body (61).

A power delivery apparatus (100) for a vehicle includes an upstream delivering portion (10) and a downstream delivering portion (20). The upstream delivering portion (10) includes: an internal input terminal (11); an external input terminal (12); and a connecting terminal (13). The internal input terminal (11), the external input terminal (12) and the connecting terminal (13) are different terminals from one another. The downstream delivering portion (20) includes: a connected terminal (23); a fuse portion (22a-22e) connected to the connected terminal (23); and a downstream output terminal (21a-21e) outputting the electric power via the fuse portion (22a-22e). The upstream delivering portion (10) and the downstream delivering portion (20) are independent members each other and are assembled to be integrated with each other to allow connecting the connecting terminal (13) and the connected terminal (23).

A method of starting an aircraft having at least a first starter/generator (S/G) and a second S/G using at least one inverter/converter and at least one of an AC power source and a first DC power source, the method includes selectively starting at least one of the first S/G or second S/G in an AC start mode and in a DC start mode.

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.

The purpose of the present invention is to swiftly start up an engine in a range in which electrical equipment having electric power supplied thereto by a battery is not reset, even in cases when the battery is insufficiently charged and the battery is deteriorated. An engine start-up device according to the present invention starts up an engine by transmitting, to the engine, the rotary force of a direct-current motor driven by a battery. The engine start-up device is provided with: a battery-voltage acquisition unit for acquiring the battery voltage of the battery; a target-current-value calculation unit which calculates, on the basis of the battery voltage acquired by the battery-voltage acquisition unit, a target current value for a motor current to be supplied from the battery to the direct-current motor; and a motor-current control unit for controlling a switching element which is connected to the direct-current motor, and through which the motor current flows, such that the motor-current value of the motor current approaches the target current value.

A permanently engaged starter assembly includes a ring gear, a return gear, and a starter gear. The return gear is fixed to a shaft of a starter return mechanism. The starter gear is arranged for fixing to a shaft of a starter motor and arranged in a torque path between the ring gear and the return gear. In an example embodiment, the ring gear has a central axis and the return gear is radially outside of the starter gear when measured from the ring gear central axis. In an example embodiment, the ring gear includes a first gear tooth, the return gear includes a second gear tooth, and the starter gear includes third and fourth gear teeth engaged with the first and second gear teeth, respectively.

An internal combustion engine including a starter is shown. A method for monitoring the starter includes determining electrical energy consumed by pinion and motor solenoids operative to activate and rotate a pinion gear of an electrically-powered motor meshingly engageable to a starter ring gear portion of a flywheel of the engine during an engine starting event. Current ringing in the pinion and motor solenoids is monitored during the engine starting even, and a fault is identified in the pinion and motor solenoids based upon the current ringing and the electrical energy consumption of the starter during the engine starting event.

The invention relates mainly to a starter (10) for a heat engine of a motor vehicle, comprising: a drive pinion (12); a pinion carrier (63) whereon the drive pinion (12) is mounted; a drive shaft (13) whereon the pinion carrier (63) is mounted such that it can slide between an idle position and a final position; and a stop (68) that is constrained to rotate with the drive shaft (13) when the pinion carrier (13) presses against the stop (68) in the final position.
