L'invention a pour but de remédier aux inconvénients exposés, pour réaliser une vanne du genre spécifié ci-dessus qui soit simple à réaliser et qui fonctionne d'une manière  The object of the invention is to overcome the disadvantages set forth in order to provide a valve of the type specified above which is simple to produce and which functions in a manner

re de celle-ci, grâce aux ouvertures de passage du disque fixe aval, et en ce que chaque évidement du disque tournant s'étend radialement vers l'extérieur, à la surface de ce disque, pour déborder au-delà des zones correspondant aux ouvertures de passage de fluide, de manière à communiquer avec des passages de purge d'air ménagés dans le corps de la vanne 2. Ainsi, grâce à l'invention, la canalisation aval reliée a la vanne se trouve toujours purgée d'air automatiquement lorsqu'on fait passer la vanne en position de fermeture La  re of the latter, through the passage openings of the downstream fixed disk, and in that each recess of the rotating disk extends radially outwards, on the surface of this disk, to overflow beyond the zones corresponding to the fluid passage openings, so as to communicate with air purge passages in the body of the valve 2. Thus, thanks to the invention, the downstream pipe connected to the valve is always air purged automatically when the valve is put in the closed position
