FIELD: mechanical engineering. ^ SUBSTANCE: proposed machine can be used as power units, pumps and compressors. It has stator consisting of two covers with several fixed cylinders in between arranged concentrically relative to common axis, ring rotors in number equal to number of fixed cylinders fitted in corresponding cylinders for synchronous rotation around axis of fixed cylinders, and blades freely moving in slots. Outer surfaces of cylinders are formed by circumferences, inner surfaces of cylinders are formed by two arcs of different radii with stepless change from one arc to the other in zone of which inlet and outlet holes for working medium are found. Arcs with minimum radii in adjoining cylinders are arranged at angular displacement of 180°, slots are located in outer surface of ring rotors, and blades are spring-loaded. Outlet hole of each inner cylinder is connected with inlet hole of adjacent outer cylinder by bypass channel. ^ EFFECT: complete utilization of energy of working medium, increased efficiency of device and its service life. ^ 3 dwg |
