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.

Abstract: A damper includes an outer tube elongated along an axis, a cylinder elongated along the axis within the outer tube, a piston disposed in the cylinder and movable along the axis, an intermediate tube attached concentrically around the cylinder, a ring press-fitted around an outer diameter of the intermediate tube, and a valve attached to the outer tube. The intermediate tube and the cylinder define an intermediate chamber radially between the cylinder and the intermediate tube. The valve is in fluid communication with the intermediate chamber. The intermediate tube includes an intermediate-tube opening extending radially through the intermediate tube. The ring includes a ring opening extending radially through the ring. The ring opening is aligned with the intermediate-tube opening. The valve is in fluid communication with the intermediate chamber through the ring opening and the intermediate-tube opening.
