Abstract: front page image
(EN)The present invention relates to a valve device (10) comprising a substrate (12) and an elastic membrane (13), the membrane being joined at least around a valve area to the substrate. The substrate comprises a first channel (16) and a second channel (17), both ending in the valve area, the first channel having in the valve area a first channel end surface (19) and the second channel having in the valve area a second channel end surface (21), wherein the area of the first channel end surface is substantially larger than the area of the second channel end surface.
(FR)L'invention concerne un dispositif (10) faisant office de soupape, comprenant un substrat (12) et une membrane élastique (13) raccordée à ce dernier au moins autour d'une zone de soupape. Le substrat comprend un premier canal (16) et un deuxième canal (17) qui aboutissent tous deux dans la zone de soupape. Dans cette dernière, le premier canal et le deuxième canal présentent respectivement une surface terminale (19, 21). L'aire de la surface terminale du premier canal est sensiblement supérieure à celle de la surface terminale du deuxième canal.
