A valve (105) controls fluid flow in a microfluidic system (100). The valve (105) has an input port adapted to receive fluid exerting a predetermined level of pressure on the valve (105) and an output port. The valve (105) has a variable sized aperture disposed perpendicular to the flow of the fluid (119). The aperture varies in size between a relatively small aperture (137) and a relatively large aperture (151). The small aperture (137) prevents the flow of the fluid (119) through the valve (105) responsive to a relatively high level of capillary forces between the fluid (119) and the valve (105) in the small aperture (137). The large aperture (151) permits the flow of the fluid (119) through the valve (105) responsive to a relatively low level of capillary forces between the fluid (119) and the valve (105) in the large aperture (151).

L'invention concerne une soupape (105) régulant un écoulement de fluide dans un système micro-fluidique (100). La soupape (105) présente un orifice d'admission conçu pour recevoir un fluide exerçant un niveau prédéterminé de pression sur la soupape (105) et un orifice de sortie. La soupape (105) présente une ouverture de dimensions variables et disposée de manière perpendiculaire par rapport à l'écoulement du fluide (119). Les dimensions de l'ouverture varient entre une ouverture relativement petite (137) et une ouverture relativement grande (151). La petite ouverture (137) empêche le fluide (119) de s'écouler dans la soupape (105) répondant à un taux relativement élevé de forces capillaires entre le fluide (119) et la soupape (105) dans la petite ouverture (137). La grande ouverture (151) permet au fluide (119) de s'écouler dans la soupape (105) répondant à un taux relativement faible de forces capillaires entre le fluide (119) et la soupape (105) dans la grande ouverture (151).
