Thermal expansion compensation shock absorber.U.S. patent: 7,004,293 Issued: February 28, 2006 Inventor: Rudi Schurmans Assigned: Tenneco Automotive Operating Key statement: The shock absorber shock absorber, device for reducing the effect of a sudden shock by the dissipation of the shock's energy. On an automobile, springs and shock absorbers are mounted between the wheels and the frame. includes a flee floating pressure tube 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 thermal expansion Increase in volume of a material as its temperature is increased, usually expressed as a fractional change in dimensions per unit temperature change. and a cap of another material that absorbs axial axial /ax·i·al/ (ak´se-al) of or pertaining to the axis of a structure or part. ax·i·al adj. 1. Relating to or characterized by an axis; axile. 2. forces, a unique rod guide assembly with a biasing member that compensates for differing thermal expansion, and a unique cylinder end assembly with a biasing member made from springs, a rubber block or pressurized pres·sur·ize tr.v. pres·sur·ized, pres·sur·iz·ing, pres·sur·iz·es 1. To maintain normal air pressure in (an enclosure, as an aircraft or submarine). 2. gas. Bob Samples, Akron Rubber Development |
