Abstract
A linear actuator includes an actuator wall, and the actuator wall includes a first wall layer having an inner surface that defines an actuator chamber. The actuator chamber is configured to accommodate an actuator fluid. The first wall layer is also subjected to a pre-load such that the first wall layer is compressively pre-stressed. The actuator wall further includes a second wall layer disposed outwardly from the first wall layer. The linear actuator further includes a piston supported within the actuator chamber, and the piston is movable in response to the actuator fluid entering and exiting the actuator chamber.
