Notice: Since RKM GbR sold all patents to an investor, this website serves as a historical record to document 16 years of development in mechanical engineering by Dr. Boris Schapiro and his team of supporters. The information presented here reflects the state of knowledge in 2009 and might not be accurate any more. Please contact Dr. Boris Schapiro for further details or information about his latest innovations.

This website is in no way affiliated with the new owner of the patents that where formerly held by RKM GbR. The new owner's Internet presence can be found at http://www.rotaryecomachines.com/index.php?lang=en.

Demos

All animations used in the presentation of the RKM technology are schematic illustrations and, thus, should not be viewed as finalized technical or production drawings. They illustrate only the basic geometry, the functional principles and the kinematics of the RKM machines.

To view the animations "online" you need the Adobe Flash Player and to watch the video downloads you need a WMV-format compatible application (for Windows: Microsoft Media Player).
