Position dependent damper for a vehicle suspension system

A damper assembly for a vehicle suspension system, comprising:

• a housing including a sidewall that defines an inner volume, a first set of apertures including a first aperture positioned at a first end of the housing, and a second set of apertures including a second aperture positioned at a second end of the housing;
• a piston disposed within the inner volume and movable between a first position and a second position;
• a first conduit extending between the first set of apertures and defining a first flow path;
• a second conduit extending between the second set of apertures and defining a second flow path;
• and
• a first bidirectional flow valve disposed along the first flow path and a second bidirectional flow valve disposed along the second flow path, wherein the first valve and the second valve comprise bidirectional flow valves having different damping characteristics, the first bidirectional flow valve and the second bidirectional flow valve providing 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 coupled to the primary damper, comprising:
• a housing including a sidewall that at least partially surrounds the primary damper, the volume between the sidewall and the primary damper defining a damping chamber, wherein the sidewall defines a set of apertures;
• a piston positioned within the damping chamber and slidably coupled to the sidewall;
• a conduit forming a flow path between the set of apertures;
• and
• a valve disposed along the flow path,
• wherein 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.
