Car-development engineers are invariably discontented with the status quo. That’s especially true in ride-and-handling development, where twin-tube shock absorbers—more accurately called suspension ...

Abstract: The spool valve is the controlling component of the hydraulic system. The wear of spool valves can lead to large gap between the spool and valve sleeve, causing greater internal leakage. It ...

One thing common to some of our favorite performance vehicles lately, from the Chevy ZR2 pickup truck to the Ford GT supercar, is the shocks –- they use Multimatic DSSV damper technology. It was just ...

Abstract: In spool valves, there is a fit gap between spool and sleeve, and the spool valve internal leakage is inevitable. For the problem of excessive leakage after assembly of qualified parts, ...

Dynamic Suspensions Spool Valve (DSSV) is a chassis suspension technology that delivers high levels of suspension damping performance. It is used on various ultra high-performance GM vehicles, ...

Determine forces on the valve spool to optimize solenoid size. Designers of spool-type, solenoid-operated hydraulic valves often face the vexing problem of increasing flow while shrinking the size of ...

This file type includes high resolution graphics and schematics when applicable. The images above are simple cross sections of a typical spool valve (left) and a poppet valve (right). (Courtesy of ...
