Abstract:
1. Fluid transfer apparatus comprising a rotatable shaft, a rotor having a first end and a second end affixed to said rotatable shaft for rotation therewith, said rotor including a plurality of axially extending flow channels extending through said rotor substantially parallel to said rotatable shaft, a plurality of flow connectors for connecting a low-pressure flow of fluid and a high-pressure flow of fluid into and out of said plurality of axially extending flow channels, a casing defining a chamber enclosing said rotor, a pair of axially movable sealing plates disposed between said first and second ends of said rotor and said casing, and pressurizing means for pressurizing said chamber by feeding a pressurizing fluid into said chamber, thereby pressurizing said rotor, said plurality of flow connectors and said pair of axially movable sealing plates, thereby forcing said axially removable sealing plates against said first and second ends of said rotor in order to reduce the leakage from said chamber to said high and low pressure flows of fluid in said axially extending flow channels.
