Filter assembly for fuel supply to actuators and fuel control system of aircraft engine and method

A method of filtering fuel flow to associated actuators and an associated fuel control system of an associated aircraft engine, comprising:

• delivering fuel from a pump to an inlet of a wash flow filter assembly;
• passing a first portion of the fuel flow to a first outlet of the filter assembly that operatively communicates with the associated fuel control system;
• filtering a second portion of the fuel flow that proceeds to a second outlet of the filter assembly that operatively communicates with the associated actuators;
• and
• increasing fuel flow velocity to maintain a desired velocity of fuel flow to the first outlet and effectively wash the filter assembly.

A wash flow filter assembly for use in an associated aircraft engine, the assembly comprising:

• a housing having an inlet and first and second outlets in fluid communication with one another;
• a filter disposed along a fluid path between the inlet and the first outlet whereby filtered material separated by the filter is washed therefrom and carried by throughflow fluid to the first outlet;
• the second outlet located downstream of the filter from the inlet and receiving filtered fluid flow therefrom;
• a movable poppet disposed along the fluid path for varying the amount of flow along the fluid path;
• and
• a recirculating passage for redirecting at least a portion of throughflow from a downstream location to an upstream location along the fluid path.
