DESIGN EVOLUTION OF THE TAYLOR DEVICES SHOCK ABSORBER, DAMPER, AND LIQUID SPRING
During his ten years of experience as an Aeronautical Engineer for Beech Aircraft and Curtiss-Wright, our founder, Mr. Paul H. Taylor, became aware of the work of Sir George Dowty in the field of fluid compressibility, and similar work by Amagot, Constaninesco, and Bridgeman.
These early studies of compressibility phenomena led to the development of various compressible material devices during Mr. Taylor's tenure as Vice President of Research at the Wales-Strippit Corporation, a machine tool manufacturer. The highlight of these developments was a mass-produced liquid spring. Over 20,000 of these were built and sold for commercial uses for dies, aircraft, ordnance, etc., during the early 1950s.
In 1955, Mr. Taylor formed Taylor Devices, Inc. for the purpose of developing an original aircraft liquid spring landing gear design that combined a spring and shock absorber into a single package. Variations of this basic product produced a pure shock absorber, a double acting damper, and a pure liquid spring. Special machines were developed to automate the production of ultra-finished bores having a half millionth of an inch surface finish (.5 micro inch), essential to the proper performance of these early, super-precision, hydraulic components.
In 1962, Mr. Taylor filed for patents on what is now the Teflon7 sealed, rod-type, liquid spring-damper, the first new type of liquid spring design in over 30 years. By 1972, Taylor Devices had manufactured over 500,000 liquid springs and liquid spring dampers utilizing the Teflon7 seal design. This seal has since been improved upon, with the associated improvement patents, to the point that millions of cycles of totally leak-free operation can be achieved without maintenance or seal replacement. In addition to Teflon7, other structural plastics are used in manufacturing seals to meet specific customer requirements, such as nuclear radiation resistance, high vacuum, or operation in environments containing caustic substances.
As a parallel program, an improved low pressure seal design was also produced, proving the basis for standard commercial shock absorber and damper designs where conventional hydraulic seals had proven to be inadequate due to leakage.
In the 1970s, patents were issued on the Taylor Devices Fluidic Damping System, the first major technical improvement in shock absorber design since 1927.
At the turn of the century, production of Taylor Shock Absorbers and Liquid Springs was well over 2.5 million units. More than 750,000 units were used as automobile bumper shock absorbers in the 1973-1976 model years. To date, over 90 U.S. patents in the field of compressible fluid technology have been issued to members of the firm. The superior design qualities and reliable operation of Taylor Liquid Springs, Liquid Spring Shocks and Shock Absorbers are well known throughout the world. Taylor Devices is now in its sixth decade as a supplier of critical shock isolation components to the United States Government.
