A hydraulic bearing is provided for a stationary gas turbine that has an oil sump with an outflow for hydraulic oil, wherein the outflow has an outflow opening which is arranged in the oil sump and an outflow line which is connected to the outflow opening. The hydraulic bearing is adapted to bring about an annular flow with a central air column when hydraulic oil flows out in the outflow line.

Hydraulic bearing for a stationary gas turbine

A seal assembly () for a gas turbine engine for controlling air flow between a diffuser () and rotor disks comprising first and second annular flange ends () and an annular seal mid-section () between and operatively connected to the flange ends (). The first and second annular flange ends () abut respective outer frame members () of the diffuser, whereby a fluid flow path is formed between the seal assembly () and the rotor disks (). The first and second end flanges () are composed of a material having a coefficient of thermal expansion that is substantially the same as a coefficient of thermal expansion of the material of the outer frame members (). In addition, the material of the seal mid-section () has a coefficient of thermal expansion that is different than that of the materials of the annular flange ends () and outer frame members ().
