Definitions

  • the invention relates to shaft packings are also connected together and toa'point'of suitable for steam turbines and particularly the low-pressure turbine, G, ata pressure to those of the kind in which a so-called slightly below atmosphere by means ofthe reservoir is connected to pockets provided piping, e. i v f v in theglands of stufiing boxes.
  • a rotary engine comprising i'ncom b-ination a plurality of pressure stages; engine shafting; glands for said shafting in connection with each of said plurality of stages,
  • a rotary engine comprising incombination a plurality of pressure stages including a sub-atmospheric stage; engine shafting; 'glandsfor said shafting in; connection with "each of said plurality of stages, each gland having at least two axially-disposed gland pockets, an outer pocket and an inner pocket a reservoir system at a pressure slightly above atmosphere to which all said outer gland pockets are connected; and a second reservoir system to which all said inner gland pockets are connected, said second reservoir system being connected to a point of said sub-atmospheric stage.
