Title:
IMPROVED THERMAL EXPANSION COMPENSATION SHOCK ABSORBER
Document Type and Number:
WIPO Patent Application WO2005030506
Kind Code:
A3
Abstract:
The present invention provides the art with a shock absorber (200) which is capable of compensating for the differing thermal expansion between two materials. The shock absorber in its various embodiments includes a free floating pressure tube (202) that is able to expand or contract axially without breaking a seal, a hybrid piston rod with a shaft of one material that compensates for differing thermal expansions and a cap of another material that absorbs axial forces, a unique rod guide assembly (114) with a biasing member (424) that compensates for differing thermal expansions, and a unique cylinder end assembly with a biasing member made from springs, a rubber block, or pressurized gas.
