<p>A rotor compressor, a rotor engine and a rotor turbine comprise a cylinder body (1), a main rotor (2) and a sub rotor (3, 3'; 31, 31') respectively. The sub rotor (3, 3'; 31, 31') is column with substantially crescent-shaped cross section, and provided with two sharp corners J and J' between which formed curves l1 and l1'. The main rotor (1) is substantially cylindrical and provided with arc-shaped grooves (6) which are distributed evenly on the outer wall of the main rotor (1). The inner wall of the cylinder body (1) is substantially cylindrical and provided with at least a set of internal projections (7, 7'). Each set of internal projections (7, 7') comprises apexes T and T'. The both sides of the apexes T and T' are connected with the inner wall of the cylinder body though curves l2 and l2' respectively. When the sub rotor (3, 3'; 31, 31') rotates to a position of the internal projections (7, 7'), the apexes T or T' are contacted with the curves l1 and l1' of the sub rotor (3, 3'; 31, 31') in order, and the sharp corners J and J' are constantly contacted with the curves l2 and l2' of the internal projections (7, 7') respectively. The rotor compressor, the rotor engine and the rotor turbine have the advantages of simple structure, steady operation, and high efficiency.</p> |
