While the new model increases the displacement, but pressor high increase correspondingly. And the cylinder ofthe space utilization has not increased accordingly. And asthe scope of pressor power use increases, the volume occupied bythe rotor has e anoverlooked part ofthe space utilization led directly down the cylinder. Toimprove space utilization cylinder, for the first time proposed anew structure ofsingle-cylinder with dual-chamber-type pressor rotor, rotor soon emptied, and inserted into astator vane, concentric with the outer cylinder, and together with the hollow rotor wall toform anew crescent-shaped hollow. Thus under the same cylinder diameter, toimprove its space utilization, and the traditional single, twin pressor pared tothe same volume, this agency has more displacement, widening ofthe rolling rotor the use pressor.
