ALTERNATING PISTON ROTARY ENGINE WITH RATCHETS

摘要

A rotary internal combustion engine has a drum-shaped combustion chamber with first (10) and second (12) paddle and hub devices that are freely rotating on a drive shaft within the chamber. Each of the paddle and hub devices having first and second paddles that are fixed diametrically opposite each other with a hub therebetween. Each of a first and second gear trains having (a) a first ratchet (30) for rotationally connecting a respective one of the hubs to the drive shaft in a first rotational direction and disconnecting one of the hubs from the drive shaft in a second rotational direction and (b) a second ratchet (32) with a gear reduction means.
