Abstract

L'invention concerne une soupape (2) et une servocommande (3) combinées avec un conteneur de transport (403, 1102) permettant d'interrompre des pressions pneumatiques basses. La soupape et la servocommande comprennent une soupape (2) et un corps de soupape (4) présentant une extrémité (5) de réservoir, un siège de soupape (23, 24) à proximité de ladite extrémité (5) du corps de soupape (4), ledit corps présentant une surface d'étanchéité (23-25); une chambre à tige (7) s'étendant à travers le corps de soupape (4) qui comprend un orifice de servocommande (22), un orifice de siège (21) et un orifice de sortie (8); une tige de soupape (13) placée de manière à coulisser dans la chambre à tige (7), la tige de soupape (13) présentant une extrémité d'obturateur (14) et un obturateur (17) fixé à ladite extrémité (14), l'obturateur (17) présentant une surface d'étanchéité (25, 26) d'obturateur permettant d'entrer en contact de manière étanche avec la surface d'étanchéité (23,24) de soupape; une servocommande (3) dotée d'un boîtier creux (100) comprenant une extrémité (10) de soupape, ladite extrémité (10) étant fixée au corps de soupape (4); une pluralité d'ensembles piston (103), chacun renfermant un piston (104) qui peut glisser dans le boîtier (100) et une cloison (105) fixée au boîtier (100), le piston (104) et la cloison (105) définissant une chambre à servocommande (107).
