Abstract
A thermal recirculation throttle valve () for an aircraft fuel system includes a housing () having a throttling valve chamber; a cover () operatively engaging a first side of the housing (); a power piston () within a power piston sleeve (), the power piston () having a first () and second face () for control pressure to act upon, the power piston () and power piston sleeve () operatively engaged with the housing () within the throttling valve chamber; a Linear Variable Differential Transformer () for measuring a linear position of the power piston () within the housing (); a throttling valve () within a throttling valve sleeve (), the throttling valve () operatively engaged with the power piston () to transfer the linear movement of the piston () between a fully extended and a fully retracted operating position; and a flow deflector () engaged with the throttling valve () for protecting the housing () from flow erosion from fuel exiting flow windows (). The throttling valve () includes a pair of fail-safe operating positions, a fully open operating position, a low leakage shutoff operating position, and a variety of variable flow operating positions between the shutoff and fully open operating positions.
