A damper housing comprising: an external tube disposed on a center axis and extending between a first end and a second end defining a chamber for receiving a working fluid, said external tube including an extended main section disposed on said center axis having a first predetermined wall thickness (T 1) extending from said first end to an intermediate end spaced from said second end, said external tube including a narrowed end section disposed on said center axis spaced from said intermediate end and extending from said second end to a proximate end spaced a predetermined distance away from said second end and adjacent to said intermediate end, an intermediate conical section extending between said proximate end of said narrowed end section and said intermediate end of said extended main section of said external tube connecting said narrowed end section with said extended main section, an end cap attached to said second end of said external tube defining said chamber between said external tube and said end cap for containing the working fluid, said narrowed end section of said external tube having a second predetermined wall thickness (T 2) with said second predetermined wall thickness (T 2) being less than said first predetermined wall thickness (T 1) of said extended main section providing an increase in internal volume of the damper housing and an increase in heat transfer of the working fluid in the chamber, characterized in that said intermediate conical section of said external tube extends from said intermediate end of said extended main section toward said center axis, and has an intermediate conical section wall thickness equal to said second predetermined wall thickness (T 2) at an internal inclination angle of between 40°-90° relative to said center axis, wherein said external tube has a cylindrical shape with said extended main section defining a first predetermined radius between said center axis and said external tube and said narrowed end section defining a second predetermined radius between said center axis and said external tube with said second predetermined radius being less than said first predetermined radius. an external tube disposed on a center axis and extending between a first end and a second end defining a chamber for receiving a working fluid, said external tube including an extended main section disposed on said center axis having a first predetermined wall thickness (T 1) extending from said first end to an intermediate end spaced from said second end, said external tube including a narrowed end section disposed on said center axis spaced from said intermediate end and extending from said second end to a proximate end spaced a predetermined distance away from said second end and adjacent to said intermediate end, an intermediate conical section extending between said proximate end of said narrowed end section and said intermediate end of said extended main section of said external tube connecting said narrowed end section with said extended main section, an end cap attached to said second end of said external tube defining said chamber between said external tube and said end cap for containing the working fluid, said narrowed end section of said external tube having a second predetermined wall thickness (T 2) with said second predetermined wall thickness (T 2) being less than said first predetermined wall thickness (T 1) of said extended main section providing an increase in internal volume of the damper housing and an increase in heat transfer of the working fluid in the chamber, characterized in that said intermediate conical section of said external tube extends from said intermediate end of said extended main section toward said center axis, and has an intermediate conical section wall thickness equal to said second predetermined wall thickness (T 2) at an internal inclination angle of between 40°-90° relative to said center axis, wherein said external tube has a cylindrical shape with said extended main section defining a first predetermined radius between said center axis and said external tube and said narrowed end section defining a second predetermined radius between said center axis and said external tube with said second predetermined radius being less than said first predetermined radius.
