Title (EN) METHOD OF PIEZOELECTRICALLY ATOMISING AND PUMPING FLUIDS AND PIEZOELECTRIC FLUID ATOMISING AND PUMPING DEVICE
(FR) PROCEDE ET DISPOSITIF DE VAPORISATION ET DE POMPAGE PIEZO-ELECTRIQUES DE FLUIDES
Abstract: front page image
(EN)A fluid atomising device having a fluid source (77) for supplying fluid to a container (80) where a pumping effect is achieved by the expansion of the volume of a portion of a piezoelectric stacked actuator (83) inside the container (80). The pumping effect pumps a portion of fluid to the space between the stacked piezoelectric actuator (83) and a second stacked piezoelectric actuator (86). Expansion of the actuators (83 and 86) results in the surface thereof facing each other impacting the portion of fluid located in said space thereby atomising the fluid into very small droplets.
(FR)L'invention concerne un dispositif ayant une source fluide (77) permettant d'alimenter un récipient (80) en fluide consistant à accomplir un effet de pompage par l'expansion du volume d'une partie d'un actionneur (83) piézo-électrique empilé logé dans le récipient (80). L'effet de pompage pompe une partie de fluide de l'espace entre l'actionneur (83) piézo-électrique empilé et un second actionneur (86) piézo-électrique empilé. L'expansion des actionneurs (83, 86) a lieu dans les surfaces opposées affectant la partie de fluide se trouvant dans ledit espace, ce qui entraîne la vaporisation du fluide en toute petites gouttelettes.
