linear actuator is a device that develops force and motion, from an available energy source, in a linear manner, as opposed to rotationally like an electric motor. There are various methods of achieving this linear motion. Several different examples are listed below.
It has a low profile and a long stroke is provided. The actuator includes a housing integrally connected to a telescoping piston. The piston may be extended by a fluid such as inflation gas provided by an inflation gas generator in fluid communication with the piston. The piston extends rapidly through a one-shot stroke. The extending piston converts energy in the fluid into motion for performing linear work. The linear actuator may be formed from a single piece of parent material through stamping processes including deep draw stamping. Alternatively, other metal forming processes may be used to form the linear actuator.
