Abstract
A fluid supply system () for turbine engine, includes a high pressure volumetric pump (), a fluid metering device () and a control valve () configured to vary the flow rate of fluid in a bypass circuit () so as to regulate the pressure difference between an input and an output of the metering device (). The control valve () includes an obturator, the variable position of which is measured by a sensor (). An electronic regulation system () compares the measured position of the obturator with a position set-point of the obturator determined as a function of a flight condition of the aircraft and/or a measured fluid temperature and corresponding to a fluid flow rate set-point in the bypass circuit (). The flow rate of the high pressure pump () is commanded so that the measured position of the obturator adapts to the position set-point.
