摘要： The invention relates to a system (10) for supplying a turbomachine with fluid, the supply system (10) comprising a low-pressure pumping unit (101) intended to increase the pressure of the fluid flowing toward a downstream circuit (50, 60). According to the invention, the downstream circuit (50, 60) divides at an inlet node (E), situated between the low-pressure pumping unit (101) and the high-pressure volumetric pump (102), into a circuit (60) supplying an injection system (62) and a variable geometries supply circuit (50). The circuit (60) supplying the injection system comprises a high-pressure volumetric pump (102). The variable geometries supply circuit (50) is configured to convey the fluid toward variable geometry devices (54) from the inlet node (E) to an outlet node (S) connecting the variable geometries supply circuit (50) to the upstream circuit (100) between two pumps (101a, 111a) of the low-pressure pumping unit.
