ABSTRACT:
A device for controlling the angular position of turning headlamps of motor vehicles comprises a correcting hydraulic circuit connecting an auxiliary distributor to the hydraulic circuit transmitting control power. The distributor is adapted to alternately be connected to a source of hydraulic liquid under pressure and to an exhaust for discharging liquid. The distributor permits a compensation for any reduction in the initial volume of the liquid in the control transmission circuit or a discharge of any excess liquid, such reduction or excess being due to variations in the thermal condition of the liquid in the circuit. Means are also provided for neutralizing the correcting circuit in all angular positions of the steering mechanism other than the straight-ahead driving position.
