Patent number: 5967268Abstract: A shock absorber demonstrating temperature conscious damping includes an auxiliary valve for passing damping fluid between the compression side and the rebound side. The auxiliary valve opens at lower temperatures and closes at higher temperatures. The valve includes an axial channel formed partially through a piston rod that terminates in a side hole on the rebound side of the piston. Movably fitted within the channel is a sliding rod valve that is movable between an open position which allows passage of the damping fluid and a closed position which prohibits passage. The valve is tubular and includes a hole formed in its side at one end. A steel spring is positioned between the blind end of the channel and the sliding rod valve. A tubular sleeve is fitted in the channel on the compression side of the piston. Between the tubular sleeve and the rod valve is positioned a spring formed from a shape memory alloy.Type: GrantFiled: March 17, 1997Date of Patent: October 19, 1999Assignee: Tenneco Automotive Inc.Inventors: Simon Anne de Molina, Bart Vandewal
