An actuator device (10) self-contained within a housing (26) and adapted to move an object. The actuator device (10) includes a movable piston (30) positioned in a cylinder portion (22) of the housing (26). The cylinder portion (22) defines a longitudinal axis, whereby the piston (30) is movable along the longitudinal axis in response to an accumulation of air pressure within the cylinder portion (22). The actuator device (10) also includes a rod (34) coupled to the piston (30) for movement with the piston. The rod (34) at least partially extends outside of the housing (26) to couple to the object. Further, the actuator device (10) includes an air compressor (14) located within the housing (26). The air compressor (14) transfers air from a location in the housing outside the cylinder portion to a location inside the cylinder portion (22). <IMAGE> |
