摘要: According to one or more embodiments of the invention, a downhole tool includes one or more actuator apparatuses to facilitate actuation of the downhole tool. The actuation apparatus includes a piston that is dynamically coupled to a tool actuator by an actuator connector in a manner that the piston and the tool actuator necessarily move in unison in response to movement of the piston in a first direction and the piston and the tool actuator do not necessarily move in unison in response to movement of the piston in the second direction.
