Abstract

Circuit hydraulique ouvert comprenant une pompe principale (P), un moteur hydraulique (M), deux conduites principales d'alimentation et d'échappement (10, 12) reliées à la pompe ou à un réservoir (R) par un sélecteur d'alimentation (14). Le circuit comprend un dispositif de valve multifonction comprenant un sélecteur multifonction (20) pour relier la conduite principale à la plus haute pression à un limiteur de pression (24) et la conduite principale à la plus basse pression à des moyens de gavage (16) et pour relier les conduites principales entre elles en les raccordant au limiteur de pression lorsque la pression dans ces conduites principales est sensiblement égale.
