Title
(EN) MEMBRANE VALVE CONTROLLED BY A PRESSURE FLUID
(FR) VANNE A MEMBRANE A COMMANDE PAR FLUIDE SOUS PRESSION
Abstract
(EN)
The valve comprises a flexible membrane (3) forming a tight wall between a controlled chamber (8) and the inside of a conduit (1). According to the invention the conduit (1) is provided with a side opening (2) having a contour of which the cross-section size L is smaller than the cross-section size D of the conduit and the membrane (3) is held in place by holding means (4, 5) carrying clamping means (7) which exert on the holding means a force transversal to the conduit (1) and outside the latter.
(FR)
La vanne comporte une membrane flexible (3) formant une cloison étanche entre une chambre de commande (8) et l'intérieur d'un conduit (1). Selon l'invention, le conduit (1) comporte une ouverture latérale (2) ayant un pourtour de dimension transversale L inférieure à la dimension transversale D du conduit et la membrane (3) est maintenue en place par des moyens de maintien (4, 5) portant des moyens de serrage (7) qui exercent sur les moyens de maintien une action transversale au conduit (1) et extérieure à celui-ci.
