Title (EN) MICROFLUIDIC MODULATING VALVE
(FR) VANNE A MODULATION MICROFLUIDIQUE
Abstract:
(EN) A valve is provided that can selectively change the size of a flow channel in a valve in order to modulate the fluid flow through the valve. The valve includes a housing (8) that defines a cavity (14), with an inlet (10) and an outlet (12) extending into the cavity. A diaphragm (30) is positioned in the cavity, where at least part of the diaphragm defines at least part of the fluid path (15). One or more electrodes (20) are fixed relative to the diaphragm, and one or more electrodes (22) are fixed relative to the housing such that the diaphragm can be electrostatically actuated to modulate the fluid flow through the valve.
(FR) L'invention concerne une vanne qui peut changer sélectivement la taille d'un canal de flux dans une vanne afin de moduler le flux de fluide à travers la vanne. La vanne comprend un boîtier (8) qui définit une cavité (14), avec un orifice d'entrée (10) et un orifice de sortie (12) s'étendant dans la cavité. Un diaphragme (30) est positionné dans la cavité, où au moins une partie du diaphragme définit au moins une partie du trajet de fluide (15). Une ou plusieurs électrodes (20) sont fixées par rapport au diaphragme, et une ou plusieurs électrodes (22) sont fixées par rapport au boîtier de telle sorte que le diaphragme peut être actionné électrostatiquement pour moduler le flux de fluide à travers la vanne.
