    Abstract: The invention concerns a turbine shaft (1), in particular for a combined high-pressure/medium-pressure steam turbine installed in a common housing (22). The turbine shaft (1) has in its interior (4) a cooling conduit (5) for the supply of cooling steam (6). The cooling conduit (5) is connected with a drain conduit (7) at one side and with a supply conduit (8) at the other. Steam-cooling of the turbine shaft (1) of a combined high-pressure steam turbine is effected through the supply of steam from the high-pressure part via the supply conduit (8) to the medium-pressure part (23) through the drain conduit (7). The invention concerns further a process for the cooling of a turbine shaft (1) of a steam turbine.

    Abstract: A variable area restrictor is disclosed that is preferably used in a turbine engine to provide improved matching between the pressure required for aerofoil cooling and the somewhat lower pressure requirement for supplying air to the interstage seals and disc cavities. In a preferred embodiment, the valve of the present invention comprises a spring loaded valve assembly with a fixed minimum flow area controlled by pre-setting a minimum dimension for the opening between an inlet and the housing or body of the valve. A pre-loaded spring maintains the lift at this minimum dimension until the pressure drop across the flow area exceeds a certain value. Above this critical pressure drop, the valve lifts, causing the flow area to increase, and thereby reducing the supply pressure that would be otherwise necessary to achieve a disc cavity flow adequate to maintain the temperatures within specifications.

    Abstract: The inter-disk cavity between turbine rotor disks is used to pressurize cooling air. A plurality of ridges extends radially outwardly over the face of the rotor disks. When the rotor disks are rotated, the ridges cause the inter-disk cavity to compress air coolant flowing through the inter-disc cavity en route to the rotor blades. The ridges eliminate the need for an external compressor to pressurize the air coolant.

    Abstract: To increase the flow density in heat exchangers (70) traversed at a high speed by at least one gaz and applied preferably to motor vehicles, the acceleration energy of the gaz is provided by the exhaust gaz of the engine. Such method allows the use of a radiator for heating (70) the vehicle or cooling (156) the engine to accumulate and increase the energy provided by the exhaust gaz. When the engine is not working hard and requires only little cooling, the residual energy of the exhaust gaz may be used to increase the flow density in the exchanger (70) and heat the vehicle; when the engine is working very hard and the heating demand is low, the flow density in the exchanger may be increased for the cooling of the engine. Preferably, the heat exchanger device is provided with an accumulator engageable in the circuit (14) of the exhaust gaz for the heating of the vehicle.
