Abstract

A damper including inner and outer tubes and a control valve. A piston is slidably disposed within the inner tube to define first and second working chambers. An intermediate member assembly is disposed annularly about the inner tube. An intermediate channel is positioned radially between the intermediate member assembly and the inner tube and a reservoir channel is positioned radially between the intermediate member assembly and the outer tube. A first unidirectional blocking valve forms a first partition between first and second intermediate channel portions of the intermediate channel. A second unidirectional blocking valve forms a second partition between the second intermediate channel portion and a third intermediate channel portion. An external control valve has a control valve inlet that is arranged in fluid communication with the second intermediate channel portion.
