摘要： The invention, which solves the old thermodynamic problem of converting pressurized heat energy into mechanical energy, is a complementary machine unit for e.g. cooling and heat pump systems. The machine has cooperating process units connected to a torque shaft for extraction of the produced mechanical energy. The machine, which replaces both an expansion valve and a condenser function, is connected to the energy collection system's suction line before the evaporator and to the pressure line after the condenser. This will thereafter be a pure heat supplier, where the delivery quantity is controlled by the machine, so the amount of energy supplied to the units is adapted for the production of the desired amount of mechanical energy and the condensing work. A 100% conversion of the collected and pressurized heat energy to mechanical energy is possible but requires adaptation of the system's pressurization.

摘要： Pompe volumétrique (1) dont le principe comprend de faire coulisser des palettes (22) dans des encoches (21) d'un rotor (20) selon un mouvement ayant une composante axiale. Ces palettes (22) suivent un guide (11), qui peut par exemple être des pistes sur des flasques (12, 13). Deux palettes (22) successives forment une cavité dont le volume varie périodiquement au cours de la rotation du rotor (20) grâce au coulissement des palettes (22), induisant de manière cyclique une aspiration du fluide dans la pompe (1) puis un refoulement.
