Title
(EN) FLUID CHECK VALVE AND FLUIDIC SYSTEMS FOR GAS VENTING
(FR) CLAPET DE NON-RETOUR DE FLUIDE ET SYSTÈMES FLUIDIQUES POUR UNE ÉVACUATION DE GAZ
Abstract
(EN)
A fluid check-valve for venting gas from a fluidic system comprises a retention body defining a fluid aperture having an upstream side and a downstream side, a hydrophilic porous material held by the retention body and disposed to cover the fluid aperture, and a hydrophobic porous material held by the retention body and disposed to cover the fluid aperture and adjacent the hydrophilic porous material. One face of the hydrophilic porous material is in fluid communication with the upstream side of the aperture, and one face of the hydrophobic porous material is in fluid communication with the downstream side of the aperture. The hydrophilic porous material is configured to retain liquid from the upstream side to hinder passage of gas from the downstream side to the upstream side, and the hydrophobic porous material is configured to hinder passage of liquid from the upstream side to the downstream side.

L'invention concerne un clapet de non-retour de fluide pour évacuer un gaz à partir d'un système fluidique, lequel clapet de non-retour de fluide comprend un corps de rétention définissant une ouverture de fluide ayant un côté amont et un côté aval, un matériau poreux hydrophile maintenu par le corps de rétention et disposé de façon à recouvrir l'ouverture de fluide, et un matériau poreux hydrophobe maintenu par le corps de rétention et disposé de façon à recouvrir l'ouverture de fluide et adjacent au matériau poreux hydrophile. Une face du matériau poreux hydrophile est en communication fluidique avec le côté amont de l'ouverture, et une face du matériau poreux hydrophobe est en communication fluidique avec le côté aval de l'ouverture. Le matériau poreux hydrophile est configuré pour retenir le liquide depuis le côté amont pour empêcher le passage de gaz depuis le côté aval vers le côté amont, et le matériau poreux hydrophobe est configuré pour empêcher le passage de liquide depuis le côté amont vers le côté aval.
