Abstract

The servo adjustment for the headlamps uses a separate hydraulic circuit for each lamp with master cylinders (16) linked to a common command control (1) on which both circuits are operated mechanically. The coupling ensures independent operation with a failure on the one circuit not affecting the other circuit. The command control has a central plunger. This plunger may be screwed to operate separate drive shafts (11, 12) and these press into servo pistons in the master cylinders.
