Special features:
-	Spherical shaped
-	No piston friction
-	Due to the new piston guide, the friction loss is reduced to a fraction of the actual engines and the effects of the centrifugal force are nearly neutralised
-	Due to the one hundred percent symmetric mounting of all moving parts, vibrations are nearly completely eliminated
Advantages:
-	Lower consumption
-	High power density
-	system simplification
-	Lower manufacturing costs
-	Simple “Scale-up” due to magnification of the sphere diameter
-	Multiple designs in row, star, box or V design are possible
-	High ecological and economical acceptance
