<p>An actuator continues to operate after deformation of a portion which would normally restrict movement between the piston and cylinder of the actuator. The piston or gland of the actuator is constructed to include segmented flanges which fracture in response to forces applied to them upon engagement of the deformation. Slots defining the segments are filled with a rubber-like material which is bonded to the piston or gland thus providing a solid structure to enable appropriate sealing while not interfering with the fracturability of the segments.</p> |
