Hydraulic compression stop with closable windows

A hydraulic compression stop (HCS) assembly comprising:

• an HCS base defining an HCS window providing fluid communication between a compression chamber of a damper and an exterior space;
• a spring guide movable relative to the HCS base by action of a piston;
• and
• a closure member attached to the spring guide and configured to selectively and progressively cover a portion of the HCS window to restrict fluid flow therethrough, with the portion of the HCS window covered varying with a position of the spring guide relative to the HCS base, wherein the HCS base includes an adapter and a replaceable disc defining the HCS window, the replaceable disc including one of a plurality of different discs, each of the different discs having a different configuration of the HCS window.

A damper assembly comprising:

• a tube defining an interior chamber;
• a piston slidably disposed in the tube and dividing the interior chamber into a rebound chamber and a compression chamber;
• and
• a hydraulic compression stop (HCS) assembly disposed at least partially within the compression chamber and including an HCS base defining an HCS window providing fluid communication between the compression chamber and an exterior space, the HCS assembly further including a closure member configured to selectively and progressively cover a portion of the HCS window to restrict fluid flow therethrough, the portion of the HCS window covered varying in response to the piston moving toward the HCS base,
• wherein the damper further comprises:
• a conical belt spring disposed in the compression chamber and including a band of material formed as spiral-shaped coil with a base adjacent to the HCS base;
• and
• wherein the closure member includes the conical belt spring progressively covering the portion of each of the HCS windows in response to the piston compressing the conical belt spring as the piston moves toward the HCS base.
