Abstract
L'invention concerne une direction assistée à commande hydraulique. Dans cette direction assistée comportant un système de refoulement hydraulique à double effet (8), dont l'espace de travail peut être chargé et déchargé au moyen d'une servo-soupape (5), et des soupapes d'amortissement (16-24), ces dernières possèdent une partie de support en forme de disque perforé (16, 18), qui peut être serrée à la manière d'une bague entretoise ou d'un disque entretoise entre une surface de support (11) d'une tubulure de raccordement (10) disposée sur le boîtier de la servo-soupape (5) ou du système de refoulement (8), et une surface de support antagoniste (15) d'une partie de raccordement (14) de la conduite (7), pouvant être raccordée à la tubulure de raccordement (10). Application notamment aux voitures de tourisme.
