www.acsource.com has these for many car makes except, of course, Toyota. I'm very interested in getting my AC working again, and thought this might be a nice addition. Anyone know of any companies that make these for Toyotas? Come to think of it, do we even have these on our cars? I don't know much at all about how AC works.

5° - 12°F colder air (at hot idle)
Reduced compressor load and extended compressor life
Improved performance when converting from R-12 to R-134a
Improved city fuel economy & emissions
Improved performance in factory R134a systems
The Smart VOV (variable orifice valve) uses system pressure and refrigerant flow to move a metering piston relative to a fixed opening in the sleeve. The piston movement is resisted by an attached spring.
When idling at high ambient temperatures, the piston shifts to a smaller metering area similar to a TXV. This compensates for the reduced compressor output and increases the cooling performance. The Smart VOV also has a unique re-open feature which reduces compressor pressure for severe idle conditions.
At highway speeds, the Smart VOV operates on a large orifice. The net result is better performance than a TXV without the complexity or reliability concerns.
Unlike a TXV, which has constantly moving parts and small internal clearances, the Smart VOV is stationary during most operating conditions and has large internal clearances. Its low friction floating design insures smooth operation and extremely long life.
