Abstract

See full text

A damper with inner and outer tubes and a piston slidably disposed within the inner tube to define first and second working chambers. A collector chamber is positioned outside the outer tube. An external control valve is positioned in fluid communication with the collector chamber. An intake valve assembly, mounted to one end of the inner tube, includes an intake valve body, intake passages, and intake valve. The intake valve body abuts the outer tube to define an accumulation chamber positioned between the intake valve assembly and a closed end of the outer tube. The accumulation chamber is arranged in fluid communication with the collector chamber. The intake valve body forms a fluid-tight partition between the accumulation chamber and a fluid transport chamber is positioned between the inner and outer tubes. The intake valve controls fluid flow between the accumulation chamber and the second working chamber through the intake passages.
