Title
(EN) CAPACITIVE PUMPING AND FLOW CONTROL
(FR) COMMANDE DE POMPAGE ET D'ÉCOULEMENT CAPACITIFS
Abstract
(EN)
Embodiments of the invention relate generally to devices and methods for pumping and controling the flow of a fluid. More particularly, embodiments of the invention relate to capacitive pumping and flow control devices and methods. In one embodiment, the invention provides a pump system having an inlet valve, an outlet valve, and a chamber between and in communication with each of the inlet valve and the outlet valve, the chamber having at least one elastic surface, wherein the chamber will dilate in response to a fluid exerting a pressure on the elastic surface, contain a quantity of the fluid when so dilated, and discharge the quantity of the fluid through the opened outlet valve.

Des modes de réalisation de l'invention portent de façon générale sur des dispositifs et sur des procédés pour pomper et commander l'écoulement d'un fluide. Plus particulièrement, des modes de réalisation de l'invention portent sur des dispositifs et sur des procédés de commande de pompage et d'écoulement capacitifs. Dans un mode de réalisation, l'invention porte sur un système de pompe ayant une vanne d'entrée, une vanne de sortie, et une chambre entre chacune de la vanne d'entrée et de la vanne de sortie, et en communication avec celles-ci, la chambre ayant au moins une surface élastique, la chambre se dilatant en réponse à l'application par un fluide d'une pression sur la surface élastique, contenant une quantité du fluide lorsqu'elle est ainsi dilatée, et déchargeant la quantité du fluide à travers la vanne de sortie ouverte.
