Abstract

L'invention concerne une vanne de commande pour fluide et notamment pour installation à vide. La vanne comporte un élément tournant 8 à l'intérieur d'un corps 1, chacun des éléments 8 et corps 1 possédant des ouvertures 2, 3 pouvant être alignées; l'élément 8 porte des éléments d'étanchéité 16, 17 qui peuvent fermer les ouvertures 2, 3 du corps 1 et un mécanisme 14, 15 pour éloigner ou rapprocher lesdits éléments 16, 17 desdites ouvertures 2, 3 grâce auquel toute friction entre les éléments 16, 17 et l'intérieur du corps de vanne est pratiquement éliminée pendant la manoeuvre de la vanne. Le mécanisme 14, 15 est, dans un mode de réalisation, constitué par des soufflets à actionnement pneumatique ou hydraulique.
