ABSTRACT:
A suspension damper includes a housing bounding a main chamber. A hydraulic fluid is disposed within the main chamber. A piston rod is selectively movable between an advanced position wherein a portion of the piston rod is advanced into the main chamber and a retracted position wherein the portion of the piston rod is retracted from the main chamber, wherein as the piston rod is moved a fluid pressure of the hydraulic fluid within the main chamber progressively increases and a portion of the hydraulic fluid passes through a passage within the housing. A control valve is at least partially disposed within the main chamber, the control valve being moved by the fluid pressure of the hydraulic fluid so as to progressively restrict the flow of the hydraulic fluid through the passage as the fluid pressure of the hydraulic fluid within the main chamber progressively increases.
