The newest Wolfhart Pump as high pressure water pump, invented and developed by Physicist Wolfhart Willimczik, US Patent No 6 152 014, Rotary Piston Machines. (the dissipation of the water in the air shows it is indeed high pressure.) Features of this most advanced pump principle: no more bearings in the piston.... more

I invented and developed this ball piston engine in the sixties/seventies last century behind the iron curtain as an environmentally friendly two stroke engine. It has a direct lubrication like a four stroke engine and also the desired asymmetrical control diagram which you can see. (The half housing, wall and one.... more
