Position dependent damper for a vehicle suspension system

A damper assembly for a vehicle suspension system, comprising:

• a housing including a wall that defines an inner volume, a first aperture positioned at a first end of the housing, and a second aperture positioned at a second end of the housing;
• a piston disposed within the inner volume and configured to move between a first position and a second position;
• a first conduit defining a first flow path that includes the first aperture;
• a second conduit defining a second flow path that includes the second aperture;
• and
• a first valve disposed along the first flow path and a second valve disposed along the second flow path, wherein the first valve and the second valve are bidirectional flow valves having different damping characteristics, at least one of the first valve and the second valve configured to provide a first level of damping as the piston extends from the first position to the second position and a second level of damping as the piston retracts from the second position to the first position.

A suspension for a vehicle, comprising:

• a wheel assembly;
• an interface configured to engage a chassis of the vehicle;
• and
• a damper assembly coupled to the wheel assembly and the interface, comprising:
• a primary damper;
• and
• a secondary damper, comprising:
• a housing including a wall that at least partially surrounds at least a portion of the primary damper, the volume between the wall and the primary damper defining a chamber, wherein the wall defines an aperture;
• a piston positioned within the chamber;
• a conduit defining a flow path that includes the aperture;
• and
• a valve disposed along the flow path,
• wherein the primary damper is configured to provide a base damping force, and wherein the secondary damper is configured to provide a supplemental damping force that varies based on the position of the piston within the chamber.
