Abstract
An electromechanical actuator having a servo valve is described. The servo valve has a valve housing having a wall surrounding the servo valve, the valve housing having a first end and a second end with the servo valve positioned between the first end and the second end. The valve housing also includes at least one debris vent positioned on an exterior surface of the wall between the servo valve and the first end of the valve housing, the debris vent having a first dimension; and, at least one fluid vent positioned on the exterior surface of the wall between the servo valve and the second end of the valve housing, the fluid vent having a second dimension. The first dimension is smaller than the second dimension.
