Title (EN) FLUID CONTROLLING MICRODEVICE AND METHOD OF MANUFACTURING THE SAME
(FR) MICRODISPOSITIF DE REGULATION DE DEBIT DE FLUIDE, ET PROCEDE DE FABRICATION DUDIT DISPOSITIF
Abstract: front page image
(EN)A fluid controlling microdevice, such as a micropump or a microvalve, wherein a stepped portion (7) is provided on an intermediate base member (1) so that a height ratio of an upper chamber (8) to a lower chamber (9) which constitute parts of a flow passage becomes t2/t1=0.2-5.0.
(FR)Microdispostif de régulation de débit de fluide tel qu'une micropompe ou une microsoupape, dans lequel, un élément de base intermédiaire (1) est pourvu d'une partie étagée (7) de sorte que le rapport entre la hauteur d'une chambre supérieure (8) et celle d'une chambre inférieure (9) se trouvant dans le passage d'écoulement soit: t2/t1=0,2-5,0.
