ABSTRACT:
A rotary engine, either prime mover--or pump or compressor--comprises as its basic element a circular casing in which is journalled rotatably a hollow, cylindrical body, the interior wall face of which ascribes a space delimited by recesses alternating with portions extending towards the center of the space, each recessed portion being diametrically opposite an inwardly extending portion, a solid cylindrical body being positioned within the space, a throughgoing bore extending across the axis of the solid cylindrical body in which bore a piston like member can perform a reciprocal movement. In the case of an internal combustion engine explosion and expansion occur in the space within the hollow cylindrical body and cause it to rotate: rotative movement is derived from a shaft of the body. A drive could be applied to the shaft so that a fluid could be compressed in the space. In use as a pump the fluid to be conveyed is sucked into the working space and expelled therefrom.
