Claim 9:
10. A damper, comprising:
an inner tube extending longitudinally between a first inner tube end and a second inner tube end along a longitudinal axis;
a piston assembly including a piston and a piston valve, said piston slidably disposed within said inner tube to define a first working chamber and a second working chamber;
an outer tube disposed annularly around said inner tube and extends longitudinally between a first outer tube end and a second outer tube end;
an intermediate tube disposed annularly about said inner tube and positioned radially between said inner tube and said outer tube;
said intermediate tube extends longitudinally between a first intermediate tube end and a second intermediate tube end;
said intermediate tube includes a first intermediate tube opening and a second intermediate tube opening that extend radially through said intermediate tube;
an intermediate channel disposed radially between said intermediate tube and said inner tube;
a reservoir chamber disposed radially between said intermediate tube and said outer tube;
a base valve assembly including a base valve body and a base valve, said base valve body having projections that abut said second outer tube end to define a fluid transport chamber positioned between said second outer tube end and said base valve body;
a slanted elliptical seal that is positioned inside said intermediate channel and divides said intermediate channel into a first intermediate channel portion and a second intermediate channel portion;
a first control valve arranged in fluid communication with said second intermediate channel portion via said first intermediate tube opening, said first control valve has a first control valve inlet and a first control valve outlet;
a second control valve arranged in fluid communication with said first intermediate channel portion via said second intermediate tube opening, said second control valve has a second control valve inlet and a second control valve outlet; and
said slanted elliptical seal is positioned at an oblique angle relative to said longitudinal axis such that said slanted elliptical seal abuts said intermediate tube between said first intermediate tube opening and said first intermediate tube end and abuts said intermediate tube between said second intermediate tube opening and said second intermediate tube end.
