AI Technical Summary
Technical Problem
Existing rotary engines face issues with complex rotor constructions, imbalance, wear, and maintenance difficulties due to eccentric vanes and radially-mobile masses, leading to energy expenditure and vibration.
Method used
A rotor-stator assembly with a component providing a fluid seal by rotating with the rotor and connected to the stator via bearings, along with a sealing mechanism using sliding connections and sealing rings to control air and gas leakage, allowing for a simpler, balanced design with easier maintenance.
Benefits of technology
The solution results in a lighter, better-balanced rotor-stator assembly with reduced air and gas leakage, facilitating easier maintenance and improved operational efficiency.

Abstract
Abstract A rotor-stator assembly for a rotary engine, compressor or pump, comprises a rotor (3, 4) arranged to rotate eccentrically in a stator chamber (1, 2), the geometry of the rotor (3, 4) being configured to provide a first fluid seal at a region of maximum proximity between the outer peripheral surface of the rotor (3, 4) and the inner peripheral wall of the stator chamber (1, 2), whereby a second fluid seal is provided by means of a component (15) rotating with the rotor, one end of which is permanently connected to the inner surface of the stator chamber (1, 2) by means of bearings and slides along the inner surface of the stator chamber (1, 2), and the other end of which is accommodated in a radially movable manner in a receptacle of the rotor (3, 4), the first and second fluid seals delimiting a first chamber portion and a second chamber portion of the stator chamber (1, 2).
