Abstract
A device may include a tool housing having an outer surface. A device may include a movable biasing element radially movable relative to the outer surface. A device may include a bore in the outer surface of the tool housing at least partially in a radial direction of the tool housing. A device may include a piston axially fixed to the movable biasing element and movable in the bore. A device may include a pressure ring coupled to the piston and positioned between at least a portion of the piston and an inner wall of the bore.
Claims20
A downhole tool comprising:
- a tool housing having an outer surface;
- a movable biasing element radially movable relative to the outer surface;
- a bore in the outer surface of the tool housing at least partially in a radial direction of the tool housing;
- a piston axially fixed to the movable biasing element and movable in the bore, wherein the piston has a first portion and a second portion, and wherein the first portion is separate and distinct from the second portion;
- and
- a pressure ring coupled to the piston and positioned between the first portion of the piston and the second portion of the piston in an axial direction.
A downhole tool comprising:
- a tool housing having an outer surface;
- a movable biasing element radially movable relative to the outer surface;
- a bore in the outer surface of the tool housing at least partially in a radial direction of the tool housing;
- a piston operably coupled to the movable biasing element and axially movable in the bore and rotatable in the bore around a transverse axis in a transverse direction to an axial direction of the bore;
- and
- a connecting rod axially coupled to the movable biasing element and the piston, wherein the connecting rod is rotatably connected to the movable biasing element.
