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.

Abstract: A shock absorber including a pressure tube, a piston assembly slidably disposed within the pressure tube, and a fluid transfer tube that extends about the pressure tube, and a reserve tube that extends about the fluid transfer tube is provided. The piston assembly divides an inner volume of the pressure tube into first and second working chambers. An intermediate chamber between the pressure tube and the fluid transfer tube is arranged in fluid communication with the first working chamber. A reservoir chamber between the fluid transfer tube is arranged in fluid communication with the intermediate chamber. An insert is disposed within the intermediate chamber, reducing the volume of the intermediate chamber and defining a fluid transfer channel between the first working chamber and the reservoir chamber.
