Abstract

L'invention concerne un système d'alimentation (10) de turbomachine en fluide, le système d'alimentation (10) comprenant un bloc de pompage basse pression (101) destiné à augmenter la pression du fluide s'écoulant en direction d'un circuit aval (50, 60). Selon l'invention, le circuit aval (50, 60) se subdivise à un nœud d'entrée (E) en un circuit d'alimentation (60) d'un système d'injection (62) et en un circuit d'alimentation (50) de géométries variables. Le circuit d'alimentation (50) de géométries variables est configuré pour acheminer du fluide vers des géométries variables (54) depuis le nœud d'entrée (E) jusqu'à un nœud de sortie (S) raccordant le circuit d'alimentation (50) de géométries variables au circuit amont (100). Le circuit d'alimentation (60) du système d'injection comprend une pompe volumétrique haute pression (102).The invention relates to a fluid supply system (10) for the turbomachine, the supply system (10) comprising a low pressure pumping unit (101) intended to increase the pressure of the fluid flowing towards a downstream circuit (50, 60). According to the invention, the downstream circuit (50, 60) is subdivided at an input node (E) into a supply circuit (60) of an injection system (62) and into a supply circuit (50) of variable geometries. The supply circuit (50) of variable geometries is configured to convey fluid to variable geometries (54) from the input node (E) to an output node (S) connecting the supply circuit ( 50) of variable geometries in the upstream circuit (100). The supply circuit (60) of the injection system comprises a high pressure positive displacement pump (102).
