Abstract
An actuator includes: a carrier including an axially elongated fluid conduit therein, the fluid conduit configured to received a ball therein; and an axially elongated ball receiving element, wherein one of the ball and the ball receiving element is configured to produce a magnetic field, and another of the ball and the ball receiving element includes an electrically conductive material, the ball and the ball receiving element configured so that the electrically conductive material is exposed to the magnetic field as the ball advances through the ball receiving element, and eddy currents are generated in the electrically conductive material that cause a repulsive force between the ball receiving element and the ball to at least one of reduce a velocity of the ball and actuate the ball receiving element.
