Actuator with integrated accumulator

A hydraulic actuator comprising:

• a main cylinder including a rod side and a cap side and a longitudinal axis extending between the rod side and the cap side, the main cylinder including inner and outer main surfaces axially aligned with the longitudinal axis;
• a piston moveable within the main cylinder and separating the rod side and the cap side of the main cylinder, the piston coupled to a rod provided on the rod side of the main cylinder;
• an accumulator cylinder including an inner and outer accumulator surfaces, the inner accumulator surface being spaced by a distance from the outer main surface to define an accumulation space between the outer main surface and the inner accumulator surface;
• and
• wherein the accumulation space is fluidly coupled with the rod side of the main cylinder, wherein the piston is operable to separate gas on the rod side of the main cylinder from hydraulic fluid on the cap side of the main cylinder, and wherein gas provided in the accumulation space is compressible and operable to bias the piston toward the cap side of the main cylinder.
