Abstract

Et verktøy nede i et brønnhull (10) omfattende et legeme (12) med spor (34), hvor legemets utside kommuniserer med legemets gjennomgående borehull (14). En muffeaktuator (30) og dor (16) er selektivt aksialt skyvbar. Aktuatoren har flenser (44) forlenget inn i sporene. Flensene har ribber på sidene som er skråstilt i en spiss vinkel mot den longitudinale akse (50) av verktøyet. Hule stenger (36) er skyvbare i sporene, og de har kanaler på innsiden som samsvarer med, og koplet til, flensenes ribber. Muffeaktuatoren glider i legemet mellom en igangsettingsposisjon og en deaktiveringsposisjon. Doren er selektivt aksialt skyvbar mellom en igangsettingsposisjon, en mellomsperreposisjon og en muffesperreposisjon. Ei sperrekule (68) sperrer (62, 70) muffeaktuatoren med hensyn på legemet i verktøyets deaktiveringsposisjon og mens doren er mellom mellomsperren og muffesperreposisjonene. I tillegg sperrer (74,70) sperrekula (68) muffeaktuatoren med hensyn på doren mens doren er mellom mellomsperren og verktøyets igangsettingsposisjoner.
