FUEL CIRCUIT OF AN AIRCRAFT ENGINE WITH A FUEL RECIRCULATING VALVE CONTROLLED BY A PRESSURE DIFFERENTIAL OF A LOW-PRESSURE PUMP OF THE FUEL SYSTEM

摘要

The invention relates to a fuel circuit of an aircraft engine comprising a fuel tank (10); an engine fuel system (20) comprising a low-pressure pump (21) and a high-pressure pump (22), and a fuel recirculating pipeline (2) connected to the engine fuel system (20); and a fuel recirculating valve (30) arranged so as to switch between an open position and a closed position according to the pressure differential of the low-pressure pump (21), said valve being able to obstruct the fuel recirculating pipeline (2) in the closed position, and to bring the fuel recirculating pipeline into communication with the fuel tank (10) in the open position.
