<p>Turbomachine fuel circuit, this circuit comprising: - a fuel return valve (FRV) connected to the main fuel circuit (102) and to a tank (110), the valve (FRV) being able to adopt a first and a second open position, which are different from one another, and a closed position, - two primary hydraulic lines (120, 130) connecting the valve (FRV) to the main circuit (102) and comprising first and second filters (125, 135) respectively, through which filters the fuel passes when the valve (FRV) is in its first open position, - two secondary hydraulic lines (140, 150) which connect the valve (FRV) to the main circuit (102) and which are positioned with respect to the first filters (125, 135) in such a way that the circulation of fuel through these secondary lines (140, 150) respectively contributes to the cleaning of the first and second filters (125, 135), the fuel circulating in the secondary lines (140, 150) when the valve (FRV) is in its second open position.</p> |
