Abstract
A hydraulic suspension damper includes a tube having an opened end and a closed end defining a compartment. A main piston is disposed in the compartment dividing the compartment into a compression chamber and a rebound chamber. A piston rod is attached to the main piston. A rod guide is disposed at said opened end. A stroke stop arrangement includes an insert and an additional piston attached to the piston rod. The insert has a narrowed section including an inner surface defining at least one recess between the distal end and the rod guide and extends axially along the insert in fluid communication with the compression chamber for allowing working liquid flow from the rebound chamber to the compression chamber during the rebound stroke. The at least one recess includes three recesses disposed equidistantly and spaced from one another.
