ABSTRACT:
A converter or valve to modulate fluid flow, that includes a fluid channel to receive the fluid which is delivered to an output. An electrically-energized bender is disposed in close proximity to the output of the fluid channel; the bender is an elongate strip secured at one end and free to move at the other end toward or away from the output to interact with fluid flow from the output. An electric energy source is connected to bias the bender electrically to provide a small, controllable separation between the free end of the bender and the output of the fluid channel to provide an orifice for fluid flow, pumping action, as the bender moves relative to the output, upon a fluid film, separate from the fluid flow, serving either to compress or to expand the fluid film to achieve damping of the bender. The bender, in a modification, is shown in the form of a disc.
