COMPRESSION ISOLATOR FOR A SUSPENSION DAMPER

摘要

A method and apparatus for a damper. The damper comprises a fluid chamber having a piston dividing the chamber into a compression and rebound sides, a reservoir in fluid communication with the compression side of the chamber, and an isolator disposed between the compression side and the reservoir, whereby the isolator obstructs fluid flow between the compression side and the reservoir. In one embodiment, a bypass provides a fluid path between the compression side and the isolator.

1. A vehicle suspension comprising:
a fluid chamber enclosed by a wall, said fluid chamber comprising:
a compression side;a rebound side; anda piston dividing said fluid chamber into said compression side and said rebound side; a bypass chamber providing a second fluid pathway between said compression side and said rebound side, said bypass chamber being in fluid communication with said fluid chamber via a set of ports disposed in said wall of said fluid chamber; and a compression isolator between said compression side and a fluid reservoir, wherein said fluid reservoir comprises a floating piston that movably seals a fluid-fillable portion of said fluid reservoir from a gas pocket of said vehicle suspension, wherein said fluid-fillable portion of said fluid reservoir collects fluid from said bypass chamber, via a third fluid pathway, as a fluid capacity of said compression side of said fluid chamber decreases during a compression stroke, wherein said floating piston transfers pressure between fluid in said fluid-fillable portion of said fluid reservoir and said gas pocket, wherein said third fluid pathway is disposed between said compression isolator and said fluid fillable portion.
