Abstract
Dispositif à coulisseaux pour obturateur anti-éruption. Il comprend deux coulisseaux opposés portant chacun une lame de cisaillement et pouvant être rapprochés l'un de l'autre afin de fermer l'alésage de l'obturateur. Au cours de ce mouvement de fermeture, les lames de ces coulisseaux cisaillent un tuyau passant dans l'alésage et l'écartent du trajet suivi par les coulisseaux. Domaine d'application : protection des puits de forage contre les éruptions.
