Abstract
What follows is the description of an improved hydraulic apparatus for the automatic adjustment of the inclination of the headlights of a motor vehicle, the adjustment being a dependent function of the axle load. The apparatus has a level sensor at each axle and each level sensor contains one metering piston and two positioning pistons. The rear axle level sensor is connected via two separate hydraulic lines to the front axle sensor, and the front axle sensor is in turn connected via two separate hydraulic lines to the positioning elements of the headlight housings. The internal construction of the two level sensors is substantially identical and is chosen such that the system is also suitable for manual adjustment.
