Fuel circuit for e.g. turbojet of aircraft, has liquid inlet and not-filtered liquid outlet that are connected to main circuit such that fuel circulation in main circuit contributes for cleaning filter

摘要

The circuit (101) has connectors (151, 152) i.e. T-connectors, for connecting a fuel return valve (FRV) to a main circuit (102). Each connector includes a self-cleaning filter, a liquid inlet and two liquid outlets such as filtered liquid outlet and not-filtered liquid outlet, where the filtered liquid outlet is connected to the valve. The liquid inlet and the not-filtered liquid outlet are connected to the main circuit such that fuel circulation in the main circuit contributes for cleaning the filter.
