Abstract

The Application describes a throttle and a method for controlling a fluid flow via a throttle . The throttle includes an inlet (618) in communication with a pressurized gas source, an outlet (610) including a selected output orifice (612), and an orifice sleeve (606) including a plurality of output orifices (612a, 612b, 612c, 612d) from which a selected output orifice (612) may be selected by rotating the orifice sleeve (606). The throttle may further include a piston (604) movable across a surface area of the selected output orifice (612), and a motor operable to move the piston (604) across the surface area of the selected output orifice (612).
