Abstract

Un outil destiné à être placé dans un train de tiges comprend un corps extérieur (11, 12, 13) ainsi qu'une manchette à brides (17, 18, 19) montée rotative et coulissante à l'intérieur du corps. Une cannelure (20) à came est formée sur un élément à effet de came (17) de la manchette à brides et vient en interaction avec des broches (21) afin de provoquer la rotation unidirectionelle de la manchette à brides dans un certain nombre de positions angulaires prédéfinies, à mesure que l'on fait aller et venir ladite manchette à brides. L'élément (18) de régulation d'écoulement de la manchette à brides est fermé intérieurement par une paroi (26) et présente des orifices (25) venant s'aligner sur des ouvertures (29) du corps et se décalant de ceux-ci, à mesure que la manchette à brides est placée dans ses positions prédéfinies. En postion d'alignement, l'écoulement dans l'outil sort de celui-ci radialement par les ouvertures (29), mais en position de non alignement, l'écoulement s'effectue à l'intérieur de la chambre (28) de l'élément central (12) du corps, et revient dans ledit élément (18) de régulation d'écoulement, en aval de la parroi (26), à travers les ouvertures (27).
