Abstract
Abstract A positive displacement machine suitable for use with incompressible or compressible fluids as a pump, motor, compressor, or engine, operates on a continuous cycle and achieves either constant or varying volume of flow by both varying the distance of the fluid volume from the main axis of rotation of the machine and progressively continuously varying the volume of the chamber containing the fluid between the inlet and outlet of the machine.
