Abstract
Generally described, aspects of the disclosed subject matter are directed to through-shaft dampers. In accordance with aspects of the present disclosure, the through-shaft dampers generally include a shaft having a piston traveling within a body, a first chamber for a damping fluid, and a second chamber for a gas. The chambers are separated by a movable wall associated with an insert and configured to provide a volumetric change of the second chamber that is inverse to a volumetric change of the damping fluid. The insert is configured such that the sealing surfaces of the movable wall do not interface the shaft during use of the damper. In this regard, a significant reduction in the total displacement traveled by the seals is realized.
