Abstract:
1. A damper assembly comprising: a damper housing at least partially defining an interior chamber; a free piston positioned in the damper housing to separate the interior chamber into a gas-filled chamber and a fluid-filled chamber; a piston assembly configured to move within the fluid-filled chamber and separating the fluid-filled chamber into an extension chamber and a compression chamber; a valve assembly separating the compression chamber into a primary chamber adjacent the piston assembly and a secondary chamber adjacent the free piston, and configured to restrict flow from the primary chamber to the secondary chamber to cause a pressure drop during compression by the piston assembly; wherein the free piston is configured to slide within the damper housing in response to fluid displacement caused by movement of the piston assembly in the fluid-filled chamber; and wherein the valve assembly is configured to be more restrictive of flow from the primary chamber to the secondary chamber than of flow from the secondary chamber to the primary chamber.
