To reduce the amount of exhaust gas leaking through the inlet side of the turbine wheel and the back face to the brazed portion and to suppress decrease in strength of the brazed portion due to increase in the temperature of the brazed portion in operation...

Fluid transfer seal assemblies (18) for transferring process fluid between a stationary component (12) and a rotating component (14), fluid transfer systems, and methods for transferring process fluid between the stationary and rotating components via a fl...

A variable nozzle for a turbocharger includes a plurality of vanes rotatably mounted on a nozzle ring and disposed in a nozzle flow path defined between the nozzle ring and an opposite nozzle wall. Either or both of the faces of the nozzle ring and nozzle ...

The present invention provides a water self-sufficient turbine system comprising: (a) a combustion turbine comprising a combustion chamber disposed between an upstream compressor coupled to a downstream turbine section; (b) a water recovery unit configured...

The labyrinth seal (1) has multiple elongated sealing lamellas (11,21), which are arranged along a longitudinal direction (LR) of the labyrinth seal side by side and at a distance from each other. A fluid discharge unit (40) is provided to affect a continu...

A low or high pressure turbine case (204) is machined on its outside surface to form circumferential notches (302). The notches may coincide with internal locations of seals (210) for the blades (208) or with "hot spots" that have been identified, for exam...

A gas turbine generally comprises a compressor, a combustor and a turbine body operatively connected to the compressor through a rotation shaft, and the turbine body is composed of a plurality of rotors formed with turbine discs and movable blades which ar...

A stationary blade (133) of a gas turbine (10), which can reduce thermal stress produced at a portion in the vicinity of a rear edge of an inner shroud (133c) of the stationary blade. The stationary blade is positioned adjacent to at least one of moving-bl...

A seal system for a four cycle engine turbocharger includes dual phase seals for limiting leakage from lubricated rotor support bearings to a turbine and/or compressor wheel of a rotor operational over an extended speed range. The dual phase seal combines ...

A heat shield pipe portion (12a) formed in an air layer (21) to protect a bearing member metal (16) from the heat of a cooling medium (B) and a seal shaft portion (12c) for forming a labyrinth seal (14) to prevent a leakage of the cooling medium are formed...
