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.
