Abstract

Une vanne empêchant le refoulement comprend un logement creux (1) comportant une vanne (5) de non-retour d'admission ainsi qu'une vanne (16) de non-retour de sortie pour des fluides s'écoulant à travers le logement, et comprend une évacuation (4) à partir du logement. Une vanne d'évacuation (10) est accouplée à ladite vanne (5) de non-retour d'admission afin d'ouvrir ladite vanne d'évacuation (10) lorsque ladite vanne (5) de non-retour d'admission est positionnée pour fermer l'admission (2). Facultativement, une vanne (9) d'aération atmosphérique est située au creux du logement.
