Abstract
A damper assembly for a vehicle suspension system includes a first damper and a second damper. The second damper includes a housing including a wall that defines an aperture, the wall and the first damper at least partially defining a chamber. The second damper also includes a piston positioned within the chamber, a conduit defining a flow path that includes the aperture, and a flow control device disposed along the flow path. The second damper is configured to provide a damping force that varies based on the position of the piston within the chamber.

A damper assembly for a vehicle suspension system, comprising:
- a first damper;
- and
- a second damper, comprising:
- a housing including a wall defining an aperture, the wall and the first damper at least partially defining a chamber;
- a piston positioned within the chamber;
- a conduit defining a flow path that includes the aperture;
- and
- a flow control device disposed along the flow path,
- wherein the second damper is configured to provide a damping force that varies based on a position of the piston within the chamber.
A vehicle, comprising:
- a wheel assembly;
- a chassis;
- and
- a damper assembly coupling the wheel assembly to the chassis, the damper assembly comprising:
- a tubular member;
- a plunger positioned within the tubular member;
- a housing that receives the tubular member, the housing including a wall that defines an aperture that is part of a flow path, a volume between the wall and the tubular member defining a chamber;
- a piston positioned within the chamber;
- and
- a flow control device disposed along the flow path,
- wherein the damper assembly is configured to provide a damping force that varies based on a position of the piston within the chamber.
