Rotor-stator assembly for a rotary engine, compressor or pump, a rotary engine and a lifting unit and device

A rotor-stator assembly for a rotary engine, compressor or pump, the rotor-stator assembly comprising:

• a stator chamber (1, 2) having a peripheral wall with an inner surface;
• a rotor (3, 4) arranged to rotate eccentrically in the stator chamber (1, 2), the rotor (3, 4) defining a receptacle and the rotor (3, 4) configured to provide a first fluid seal at a region of maximum proximity between an outer peripheral surface of the rotor (3, 4) and the inner surface of the peripheral wall of the stator chamber (1, 2);
• bearings and slides along the inner surface of the stator chamber (1, 2);
• and
• a component (15) rotating with the rotor and having a first end and a second end, the first end being permanently connected to the inner surface of the peripheral wall of the stator chamber (1, 2) by means of the bearings and slides, and the second end being accommodated in a radially movable manner in the receptacle of the rotor (3, 4);
• wherein the first and second fluid seals delimit a first chamber portion and a second chamber portion of the stator chamber (1, 2).
