  • Patent number: 9863426
    Abstract: A compressor rotor comprising a pinion shaft which has multiple interconnected segments that are arranged axially one behind the other and including a multipart seal which seals the pinion shaft is provided. The pinion shaft has a rotor segment which supports a rotor, a connection segment, and a toothed segment arranged axially between the rotor segment and the connection segment, the toothed segment having a toothing at each of the two ends of the toothed segment. The toothed segment is held axially between the rotor segment and the connection segment via toothings by means of corresponding mating toothings at ends of the rotor segment and the connection segment, and a multipart seal sealing element which is connected to the toothed segment in an at least force-fitting manner is arranged on said toothed segment.

  • Patent number: 8142151
    Abstract: An intermediate housing floor for a fluid kinetic machine is provided. The intermediate housing floor includes a partial joint at which the intermediate housing floor may be divided during installation and/or removal into/from the fluid kinetic machine and is made up of at least two overlapping partial joint surfaces at sections of the intermediate housing floor that face one another.

  • Patent number: 5765998
    Abstract: A process for ensuring the operability of gas seals in turbocompressors, especially turbocompressors with a higher operating pressure and a higher shutdown pressure which have gas-lubricated sliding-ring seals for sealing the shaft lead-throughs and in which cleaned gas is fed to the gas-lubricated sliding-ring seals from a higher-pressure tapping location proceeding from the turbocompressor. While the turbocompressor is shut down the pressure of the gas outside of the turbocompressor is increased above the pressure level prevailing during shutdown using a pressure booster unit, and the gas is fed in a cleaned state to the gas-lubricated sliding-ring seals.
