Abstract
A compact, easily manufactured, axisymmetric mechanism can be configured to change the magnitude of a short-movement linear motion, or also reverse the movement direction, of an actuator for control of movable elements. The mechanism is bidirectional and reversible, functioning symmetrically, and does not contain any gears nor lead screw threads. It is constantly loaded, so that force change is achieved without mechanical backlash, introducing hysteresis. The movement conversion is generally proportional and suitable for use in actuating a fluid control valve intended for modulating the control of fluids.
