Abstract:
1. A strut assembly having a suspension damper comprising: a substantially vertically-oriented tube having a top end and a bottom end; a rod guide assembly closing the bottom end of the tube; a damping piston assembly disposed within the tube and slidably mounted therein for reciprocal movement in the tube, wherein the tube is substantially filled with a fluid having a specific gravity that damps the reciprocating movement of the damping piston assembly within the tube; a piston rod connected to the damping piston assembly and extending through the tube and the rod guide assembly; a rebound eat-off disk suspended in the tube between the rod guide assembly and the damping piston assembly and cooperating with the damping piston assembly to provide a rebound cut-off effect between the rebound cut-off disk and damping piston assembly; and a spring disposed between the rebound cut-off disk and the rod guide assembly, wherein the disk has a specific gravity that is greater than the specific gravity of the fluid, whereby the disk moves in the fluid toward the bottom end in response to its own weight.
