Abstract

L'invention concerne une unité d'alimentation en pression pour un système hydraulique comprenant au moins un circuit consommateur (BK1, BK2) et comprenant au moins une pompe rotative (Pa, Pb). Soit au moins une pompe rotative (Pa, Pb) permet de réaliser un refoulement volumique dans au moins une direction de refoulement dans au moins un circuit consommateur (BK1, BK2) de telle manière qu'un volume refoulé (V p. ex. en [cm3]) défini en fluide hydraulique est refoulé en particulier pour établir une pression (Pauf), pour réduire une pression (Pab) et/ou pour ajuster un agrégat. Soit l'invention prévoit au moins deux pompes rotatives (Pa, Pb), la pression dans au moins un circuit consommateur (BK1, BK2) pouvant être établie et réduite au moyen d'une alimentation en courant correspondante de l'entraînement (Ma, Mb) électromotorisé correspondant d'au moins une des pompes rotatives (Pa, Pb).
