Jeff,
The bleeder valve you are referring to is the Stahlbus valve. If you go to the web site:
www.tost.de, you will find information in English about this valve, plus a cartoon-style animation on how it works. To get there faster, try this in your browser:

They also offer a small plastic pump to help with the job. I think their products are very well designed, and bought some for myself. They are based on motocycle technology and maintenance. I have not had the opportunity to try them yet.
Note that the web site is in Germany, and while I had no problem getting them here in France, you can also order them from the add in the December Sport Aviation, page 75. Please let us know if you put them in a give them a try.
