A vehicle headlight positioning device comprising a pivoting headlight support and a linear actuator comprising a housing (), an electric stepping motor with a rotor having a part in the form of a nut, and a linear-movement screw engaging the nut part of the rotor. The screw has a coupling portion arranged at one of its ends and is intended to transversely engage a coupling portion part integral with a pivotable headlight support.

Headlight positioning device

A piston within the body of the valve is connected to an actuator and is integral with stops. After a first stroke of the piston from its position against the first seat, the first stops entrain second stops integral with a second piston, to entrain this with the first piston over a second stroke, from the position of application of the second piston to its seat. This feeds air-assisted injectors through the outlet over the first stroke, and in addition, over the second stroke to admit air through the outlet bypassing a throttle valve. Control of a single actuator allows the airflow to be regulated through each of the two outlets in succession.
