Abstract
L'invention concerne une installation hydraulique notamment pour des véhicules utilitaires tels qu'une machine de chantier, cette installation comportant une pompe d'agent de pression (2) qui alimente un consommateur en agent de pression (3). L'invention est caractérisée en ce que la pompe d'agent de pression (2) extrait un agent de pression (3) d'un espace de fluide basse pression (4) de l'installation hydraulique (1) et le transporte dans un espace de fluide haute pression (5) disposé entre un consommateur et la pompe d'agent de pression (2), et en ce que, par le mouvement d'un piston (6,7) dans l'espace de fluide haute pression (5) ou dans l'espace de fluide basse pression (4), un dispositif d'alimentation secondaire (8) peut être actionné, ce qui permet d'alimenter l'espace de fluide basse pression (4) en agent de pression (3) à partir d'un réservoir d'agent de pression (9).
