| 摘要 |
<p>The invention concerns a system for supplying fluid 10, such as fuel, to a turbine machine. The system comprises a low pressure pumping unit 101 increasing the pressure in a fuel supply line flowing towards a downstream circuit 50, 60. The downstream circuit is subdivided at an inlet node E into an injection system supply circuit 60 and a variable geometries supply circuit 50, such as a fuel-hydraulic circuit. The variable geometries supply circuit carries fuel towards the variable geometries from the inlet node to an outlet node 5 connecting the variable geometries supply circuit to the fuel supply line. The injection system supply circuit comprises a high pressure volumetric pump 102 and a pressure loss regulator 20 configured to regulate pressure losses in the injection system supply circuit. The pressure loss is regulated as a function of the pressure difference between the inlet of the regulator downstream from the high pressure pump, and low pressure inlet in fluid communication with a point P upstream from the high pressure pump.</p> |
