Abstract
The invention relates to a hydropneumatic suspension component such as a gas charged damper. The invention further relates to a floating piston for a hydropneumatic suspension component. Uses of adsorbent material and/or open-cell foam are also disclosed.
Claims36
A hydropneumatic suspension component comprising:
- a variable-volume chamber having a first portion volume for holding a pressurised gas and a separate second portion volume for holding a non-gaseous fluid used as a damping medium, wherein the first portion volume is isolated from the non-gaseous fluid in the second portion volume, and further wherein the first portion volume comprises a mass of an adsorptive material and/or an open-cell foam to limit the build-up of pressure as the first portion volume is compressed in use by the non-gaseous fluid provided in the second portion volume.

A hydropneumatic suspension component comprising:
- a variable-volume chamber having a first portion volume for holding a pressurised gas and a separate second portion volume for holding a non-gaseous fluid used as a damping medium, wherein the first portion volume is provided in one or more conduits that partially surround an outer surface of a housing comprising the second portion volume.
A floating piston for a hydropneumatic suspension component comprising:
- a main body comprising a chamber having an opening, and in which the chamber contains a mass of adsorptive material and/or open cell foam to limit the build-up of pressure in a hydropneumatic suspension component.
