Abstract
A damper assembly with a hydraulic compression stop (HCS) includes a tube defining an interior chamber. The damper assembly also includes a piston assembly slidably disposed in the tube. The piston assembly includes an HCS piston. The HCS piston includes a piston extension with a piston ring disposed thereupon. The damper assembly also includes an HCS sleeve. The HCS sleeve includes an HCS body having a tubular shape and defining a chamfer opening for receiving the HCS piston. The HCS body defines a plurality of ribs extending radially inwardly from the chamfer opening and configured to guide the HCS piston apart from the chamfer opening as the HCS piston enters the HCS sleeve.

A hydraulic compression stop (HCS) sleeve for a damper assembly, comprising:
- an HCS body having a tubular shape and defining a chamfer opening for receiving an HCS piston, the HCS body defining a plurality of ribs extending radially inwardly from the chamfer opening and configured to progressively guide the HCS piston apart from the chamfer opening as the HCS piston enters the HCS sleeve,
- wherein at least one rib of the plurality of ribs defines a sloped surface facing out of the HCS body and toward the HCS piston with the HCS piston outside of the HCS sleeve, and includes a lower surface adjacent to the sloped surface and extending generally parallel to a cylindrical inner surface of the HCS body,
- wherein the at least one rib is located at the chamfer opening, wherein the HCS body has a variable thickness at the chamfer opening, the chamfer opening sloping inwardly from an annular rim of the HCS body to a cylindrical inner surface of the HCS body.
