Abstract

L'invention concerne un système hydraulique pour commander deux embrayages dotés chacun d'un cylindre récepteur (1, 2) alimenté en huile sous pression par une unité pompe (3) réglable et par une première (21) et une deuxième (22) conduite sous pression. L'invention vise à réaliser un système hydraulique à la fois simple, bon marché, peu encombrant et doté d'une sécurité intrinsèque. A cet effet, le système est équipé d'une seule unité pompe (3) réversible où, en fonction du sens de refoulement de la pompe (4), l'un ou l'autre raccord (7, 8) de la pompe (4) sert de raccord d'aspiration et l'un ou l'autre raccord (8, 7) de raccord de refoulement. Les raccords (7, 8) sont reliés au réservoir (17) par des clapets anti-retour (13, 15) se fermant en cas de pression positive et à la conduite sous pression correspondante (21, 22) par des deuxièmes clapets anti-retour (14, 16) s'ouvrant en cas de pression positive.
