A check valve 10 for a fluid passageway 12 or 14 of a pressure balancer 16 or the like, and having a base plate 40 with an opening 62 therethrough connected in the passageway 12 or 14. The underside 42 of the base plate 40 disposed in the passageway 12 or 14 to face normal flow therein and the upperside 44 facing the opposite direction. A substantially "U" shaped frame member 79 is connected on the upperside 44 of the base plate 40. The frame member 79 carries two leg members 52 and 54 extending from the upperside 44 of the base plate 40 on opposite sides of the opening 62 with a bridge member 72 carried by the leg members 52 and 54 to span the opening 62. A closure member 92 is disposed on the upperside 44 of the base plate 40 adjacent the opening 62. A spring member 80 is connected between the frame member 79 and the closure member 92 normally to urge the closure member 92 to close theopening 62 whenever the flow in the passageway 12 or 14 is less than 5 psi.
Cette invention concerne un clapet de retenue 10 à placer dans un passage d'écoulement 12 ou 14 d'un équilibreur de pression 16 ou appareil analogue, ledit clapet comportant une plaque d'assise 40 à ouverture 62 donnant sur le passage 12 ou 14. La face inférieure 42 de la plaque d'assise 40 placée dans le passage 12 ou 14 fait face à l'écoulement normal du liquide et sa face supérieure est orientée dans le sens opposé. Un cadre sensiblement en forme de U 79 est fixé à la face supérieure 44 de la plaque d'assise 40. Ce cadre 79 comprend deux branches 52 et 54 qui partent de ladite face supérieure 44 de ladite plaque d'assise 40 de part et d'autre de ladite ouverture 62 et une traverse 72 faisant le pont entre lesdites branches 52 et 54, au-dessus de l'ouverture 62. Un obturateur 92 est placé sur la face supérieure 44 de la plaque d'assise 40, à proximité de l'ouverture 62. Un ressort 80 raccordé d'une part à la traverse 79 et d'autre part à l'obturateur 92 pousse celui-ci dans l'ouverture 62 pour la fermer dès que la pression d'écoulement dans le passage 12 ou 14 chute sous 5 lb/po2.
