Abstract:
An actuation system to control flow of a fluid includes a body including an axial cavity and a valve in fluid communication with the axial cavity, the valve including a closing member moveable into and out of a closed position against the valve seat, and a resistance member. Fluid from the axial cavity can flow through and out of the valve when the closing member is out of the closed position and the closing member is biased into or out of the closed position by a force applied by the resistance member. The closing member is movable out of or into the closed position upon a rotational speed and fluid pressure within the axial cavity being sufficient to overcome the force applied by the resistance member.
