Abstract
A strut assembly including a first cylinder, a second cylinder configured to reciprocally move within the first cylinder, and a damper assembly positioned within the first cylinder. The damper assembly includes a housing having opposing first and second ends, a floating piston in the housing and a damper piston positioned between the floating piston and the first end of the housing. The damper piston divides the housing into first and second chambers, where the first and second chambers include a hydraulic fluid that provides resistance to the movement of the damper piston in the housing. The strut assembly also includes a gas spring in the first and second cylinders, where the gas spring includes a pressurized gas contained within the first and second cylinders.
