  • Patent number: 11608872
    Abstract: A damper assembly comprises a main tube defining a fluid chamber. The main tube includes a first section, a second section, and an intermediate portion. A sleeve is disposed about the main tube. An external tube is disposed about the main tube and the sleeve. The external tube defines a compensation chamber between the sleeve and the external tube. A main piston divides the fluid chamber into a rebound chamber and a compression chamber. A piston rod couples to the main piston for moving the main piston between a compression stroke and a rebound stroke. The sleeve is in an abutment relationship with the second section of the main tube, radially spaced apart from the first section of the main tube, defining a compartment extending between the sleeve and the first section of the main tube. A housing for the damper assembly is also disclosed herein.
