MULTIFLEX COUPLING

摘要

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.

主权项

1. A mechanical motion converter comprising:
an active element; a reactive element; a pivot pin; and at least one rocker element for pivoting about the pivot pin, the rocker element being disposed axially between the active element and the reactive element; wherein the active element, the reactive element, and the at least one rocker element are joined together and translate axially in response to a force exerted by an actuator.
