Title (EN) UNITARY ACTUATOR VALVE FOR DOWNHOLE OPERATIONS
(FR) SOUPAPE D'ACTIONNEUR UNITAIRE POUR OPÉRATIONS DE FOND DE TROU
Abstract:
(EN) A member includes a unitary body defining a first portion integrally joined with a second portion through one or more shear tabs. The first portion defines a piston portion having a first end section including an activation member, a second end section, and an intermediate portion extending therebetween. The second portion defines a piston ring member disposed adjacent the first end section and includes a first section having a first diameter and a second section having a second diameter that is greater than the first diameter.
(FR) L'invention concerne un élément comprenant un corps unitaire définissant une première partie reliée d'un seul tenant à une seconde partie par l'intermédiaire d'une ou de plusieurs pattes de cisaillement. La première partie définit une partie de piston présentant une première section d'extrémité comprenant un élément d'activation, une seconde section d'extrémité, et une partie intermédiaire s'étendant entre celles-ci. La seconde partie définit un élément de segment de piston disposé adjacent à la première section d'extrémité et comprend une première section présentant un premier diamètre et une seconde section présentant un second diamètre qui est supérieur au premier diamètre.
