A truck brake system air compressor improves fuel efficiency by reducing the parasitic horsepower load during an unloaded cycle. By using a ceramic valve member, having a decreased mass over current valve members, the valve lift can be increased thereby increasing the flow area past the valve seat. This reduces the horsepower required to run the compressor in the unloaded mode and reduces heat generation which is otherwise detrimental to other components of the compressor assembly. In addition, using a ceramic material provides a valve member that has a strength nearly equivalent to that of the conventional steel valve member, and allows alternative configurations to be used in an effort to …

Why it's free to use
- Filed September 9, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 9, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 9, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
