Patent ID: 7641029

Claim:
A piston assembly for a shock absorber comprising: a cylindrical body defining a central axis and having a first surface facing a compression side and a second surface facing a rebound side; and an outer band portion extending tortuously about an outer circumference of said cylindrical body wherein said outer band portion has an outermost compression side edge and an outermost rebound side edge longitudinally spaced apart from each other along said central axis and wherein said outer band portion is defined by a band height that is less than a height dimension extending from said outermost compression side edge to said outermost rebound side edge in a direction parallel to said central axis, and wherein said band height is defined as extending between a first band edge and a second, band edge with said band height changing orientation relative to said central axis as said outer band portion winds about said outer circumference such that said band height is parallel to said central axis in certain orientations and is transverse to said central axis in other orientations.
