Abstract
A damper assembly for a vehicle suspension system includes a primary damper and a secondary damper coupled to the primary damper. The secondary damper includes a housing, a piston, a conduit, and a valve. The housing includes a sidewall that defines a set of apertures and at least partially surrounds the primary damper, and the volume between the sidewall and the primary damper defines a damping chamber. The piston is positioned within the damping chamber and is slidably coupled to the sidewall. The conduit forms a flow path between the set of apertures, and the valve is disposed along the flow path. The primary damper provides a base damping force, and the secondary damper provides a supplemental damping force that varies based on the position of the piston along the housing.
