Draper 33402 Rotor DSH1750 DSH450 DSH1250

DRAPER 33402 ROTOR

The rotor has three convex faces, each of which acts as a piston. Each face of the rotor has a pocket in it, which increases the displacement of the engine, allowing more space for air/fuel mixture. At the apex of each face is a metal blade that forms a seal to the outside of the combustion chamber.
