Abstract
A suspension damper including an actuator and a static fluid damper is provided. The actuator includes a first housing and a second housing positioned within the first housing and coaxially aligned with the first housing along an axis of the actuator. The second housing defines a passage. A piston is slidably positioned within the passage of the second housing to define a first chamber and a second chamber. A divider is positioned between an inner surface of the first housing and an outer surface of the second housing to define a third chamber and a fourth chamber. The static fluid damper includes a first damping chamber, a second damping chamber, and a third damping chamber. A separating member is positioned within the third damping chamber to define a gas chamber. First and second flow passages provide fluid communication between the actuator and the static fluid damper.
