  • Sealing arrangement for a joint between two stator parts of a turbomachine
    Patent number: 4279424
    Abstract: The sealing arrangement for sealing the gap between two relatively movable stator parts includes a split ring which is adapted to twist and expand within a V-shaped notch formed by the two parts. The ring is held in place by a coil spring and the split in the ring is bridged and sealed by a locking member which allows the ring to expand and contract radially.

  • Method and apparatus for cooling turbomachines
    Patent number: 4003200
    Abstract: An auxiliary blower is connected to the gaseous supply line to the axial compressor to deliver a gaseous medium, such as air, under pressure to the compressor when the rotor has been shut-off and slowed to a reduced speed. The delivered gaseous medium allows the rotor to continue rotating at the reduced speed while cooling of the rotor and vanes takes place in a uniform manner. The drive power for the blower amounts to 0.05% to 0.1% of the useful power in full-load operation of the compressor.
