A damper including inner and outer tubes is provided. A piston is slidably disposed within the inner tube. An intermediate tube is positioned radially between the inner and outer tubes. The intermediate tube extends between first and second intermediate tube ends. An intermediate channel is disposed radially between the intermediate and inner tubes. A slanted elliptical seal is positioned inside the intermediate channel and divides the intermediate channel into first and second intermediate channel portions. A first control valve is in fluid communication with the second intermediate channel portion via a first intermediate tube opening. A second control valve is in fluid communication with the first intermediate channel portion via a second intermediate tube opening. The slanted elliptical seal abuts the intermediate tube between the first intermediate tube opening and the first intermediate tube end and between the second intermediate tube opening and the second intermediate tube end.
