Abstract
An apparatus for activating a wellbore tool includes a cylinder, a shaft, and a pressure dissipater. The cylinder has a first inner surface defining a smooth bore section and a second inner surface adjacent to the first inner surface. The shaft has a piston section that includes at least one seal forming a fluid seal with the first inner surface when the seal is at a nominal diameter. The pressure dissipater is formed along the second inner surface of the cylinder, the pressure dissipater contacts and physically destabilizes the at least one seal after the at least one seal exits the smooth bore section.
