Bistable miniature valve

Torna indietro

Abstract

A bistable minivalve includes a movable component, an actuator that is electrostatically, magnetically, or mechanically coupled to the movable component for controllably switching the movable component between open and closed states, and a casing providing structural support. The movable component has an actuation surface [ 300] movably positioned in the valve conduit and a bistable element attached to the actuation surface providing mechanical stability to the open and closed states of the movable component. The bistable element may be realized as a pair of elastic buckling beams [ 302, 304] attached at their midpoints to opposite sides of the actuation surface. Optionally, there may also be elastic support beams [ 306, 308] attached at their endpoints to the actuation surface and attached at their midpoints to the elastic buckling beams.
