Rotary piston engine for use as a drive or a pump

摘要

The rotary piston engine or a paddle cell pump operated at one side, uses paddle blades (4) of a compound material using a carbon skeleton with carbon fiber reinforcement and a plastics matrix also enriched with carbon. The paddle blades (4) are structured to lie at a tangent to the dia. of a projected circle round the rotor (2), and through the rotor center, at an angle of 25-35 deg , so that the paddle axis forms a dia. which is 0.4-0.6 times the rotor radius.
