<p>In a branch hydraulic line (6a, 6b) upstream of the distribution servovalve (1) of the assisted steering system, a valve mechanism with electromagnetic control (10) is situated, which comprises a valve member biased by an electromagnetic actuator (16) having two states, energized and unenergized, which is controlled by a switch (20a, 20b) actuable by the lever (21) of the gear changing mechanism of the vehicle so as to close the branch line (6a, 6b) during engagement of the parking gears (first and reverse) and thus to obtain maximum hydraulic assistance power, the assistance power being reduced during other conditions of use (driving along the road) of the vehicle.</p> |
