Abstract

Soupape de sécurité anti-bulles pour circuit de liquide à faible pression, en particulier pour perfusion médicale. Cette soupape de sécurité comprend une enceinte d'admission du liquide qui est en partie délimitée par une membrane coopérant avec un siège à conduit de sortie du liquide de sorte que le liquide présent dans l'enceinte doit passer dans l'interface membrane-siège pour s'écouler de façon laminaire vers ledit conduit, cette enceinte présentant un passage vers l'atmosphère pour l'évacuation de toute bulle d'air éventuelle admise.
