摘要： L'invention propose un dispositif de vanne cryogénique comprenant un corps de vanne (1) dans lequel circule un fluide cryogénique et un clapet (2) disposé dans le conduit et relié à une tige de commande (3) pour manoeuvrer le clapet entre une position de fermeture et une position d'ouverture de manière à contrôler le débit du fluide cryogénique. Le dispositif comprend en outre un actionneur pneumatique (4) comprenant une chambre (41) renfermant un piston (42) en liaison avec la tige de commande (3), la chambre (41) étant alimentée avec un gaz de commande pour positionner le piston dans une position déterminée. L'actionneur est fixé au corps de vanne par l'intermédiaire d'une chambre (51) interposée entre l'actionneur (4) et le corps de vanne (1) de manière à découpler thermiquement l'actionneur du corps de vanne pour maintenir la température de l'actionneur et, par conséquent celle du gaz du commande, à une température intermédiaire entre la température du corps de vanne et la température ambiante. La chambre (51) est en surpression afin d'empêcher des entrées externes et d'évacuer les éventuelles fuites dans le dispositif.
