Le dispositif de régulation 1 est constitué par une boite à soupape 2, un bottier de membrane inférieur 3 et un bottier de membrane supérieur 4 qui sont réunis entre The regulating device 1 consists of a valve box 2, a lower membrane box 3 and a top membrane box 4 which are joined between

Dans la boîte à soupape 2 est disposée une sou- In the valve box 2 is arranged a
pape 7 qui, au moyen d'un organe de fermeture 8, repose sur pope 7 which, by means of a closing member 8, is based on
un siège de soupape 9.a valve seat 9.
L'extrémité libre 10 de la soupape 7 s'engage dans un espace Il constitué par les bottiers de membrane 3, 4 et au moyen d'une vis 14 elle est réunie à un disque 13 qui porte un piston 12 Entre le disque 13 et le piston 12 est fixée une membrane 15 qui est pincée en 16 entre les bottiers de membrane 3, 4 et sépare l'une de l'autre une première chambre de pression 17 et une deuxième chambre de pression 18 La soupape 7 est maintenue dans la position fermée par un ressort de pression 19 qui prend appui d'une part sur le piston 12 et d'autre part sur une paroi 20 The free end 10 of the valve 7 engages in a space 11 formed by the membrane housings 3, 4 and by means of a screw 14 it is joined to a disc 13 which carries a piston 12 between the disc 13 and the piston 12 is fixed a membrane 15 which is clamped at 16 between the membrane housings 3, 4 and separates from one another a first pressure chamber 17 and a second pressure chamber 18 The valve 7 is maintained in the closed position by a pressure spring 19 which is supported on the one hand on the piston 12 and on the other hand on a wall 20
