Abstract
Cette invention concerne une valve de commande Cette valve comprend un boisseau muni à sa périphérie d'au moins un canal de passage du fluide et associé à un clapet de retenue Celui-ci est constitué par une bague ouverte qui entoure le boisseau en forme de chemise et qui assure l'obturation de ce canal dans un sens d'écoulement Cette bague peut être élastique et logée dans une dépression en forme de décolletage du boisseau. Une valve de ce type est utilisable pour toutes les applications exigeant la commande de l'écoulement d'un fluide, par exemple entre une pompe et un appareil d'utilisation, afin d'éviter l'écoulement intempestif du fluide à partir de cet appareil, notamment en cas de rupture d'un conduit
