Abstract
Une coulisse est révélée destinée à une utilisation dans un trou de forage et comprend un logement extérieur; un mandrin intérieur; une chambre de fluide étanche entre les deux; un clapet à lintérieur de la chambre de fluide, présentant une face de surface de restriction, pendant linstallation, une surface de restriction coopérante sur un du mandrin intérieur et du logement extérieur et une surface de pression faisant face à lautre; la surface de restriction coopérante agissant pour installer la coulisse pour un déplacement par coulissement dans une première direction, vers le haut du trou ou vers le bas du trou; la surface de pression étant exposée au fluide à lintérieur de la chambre de fluide quand la coulisse est installée et faisant pression vers le haut pour ladite coulisse; la surface de pression étant crantée pour entraîner un mouvement radial inégal de la surface de restriction vers la surface de restriction coopérante lorsque la coulisse est installée et faisant pression vers le haut pour ladite coulisse; et des surfaces de repêchage à la coulisse sur le mandrin intérieur et le logement extérieur respectivement en vue de repêcher à la coulisse le contact avec chacun pendant ledit repêchage à la coulisse.
