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.
Claims20
An electromechanical actuator, comprising:
- a servo valve;
- 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 comprising:
- 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;
- wherein the first dimension is smaller than the second dimension.
A method of operating an actuator in mud having debris and lost circulation material, comprising:
- closing a servo valve positioned within a valve housing, the valve housing having a plurality of fluid vents positioned downstream of the servo valve and a plurality of debris vents positioned upstream of the servo valve, dimensions of the plurality of fluid vents are less than dimensions of the plurality of debris vents;
- wherein closing of the servo valve creates a first fluid path wherein fluid flows from a mud pump at a surface into the plurality of debris vents and out of the plurality of fluid vents shielding the servo valve from debris and lost circulation material.
An actuator, comprising:
- a servo valve;
- and,
- a valve housing having a plurality of fluid vents and a plurality of debris vents configured to form a fluid path wherein the fluid vents and debris vents enable flow of debris via the fluid path from the valve housing regardless of state of the servo valve.
