Abstract

1,175,737. Exhaust gas turbo superchargers. D. NAPIER & SON Ltd. April 22, 1968 [April 21, 1967], No. 18447/67. Heading F1G. The invention relates to an engine supercharger in the form of a turbo-charger in which the turbine rotor is cooled by compressed air bled off from the compressor into a cooling air chamber defined in part by the turbine rotor, the cooling air escaping from the chamber into the gas flow path downstream of the turbine rotor. A port is provided communicating the bleed air passageway with atmosphere, the port being provided with a non- return valve so that the port would normally be closed, the valve being opened in the event that the pressure in the bleed air passageway should fall below atmospheric pressure. The turbocharger shown comprises a turbine rotor 6 and a centrifugal compressor rotor 4 mounted on a common shaft 2. Air is bled from the compressor discharge through a labyrinth seal 28 and ports 26 into a chamber 24, the air passing from the chamber 24 through ducts 22 to a cooling air chamber 20 adjacent the downstream side of the turbine rotor disc. The air discharges from the chamber into the exhaust gas flow downstream of the turbine rotor. A port 36 is provided communicating the bleed air chamber 24 with atmosphere, the port being closed in normal operation by a non-return valve 38. Should the air pressure in chamber 24 fall below atmospheric the valve 38 will open so preventing the possibility of turbine exhaust gases passing into the compressor assembly.
