  • Drain removal monitoring equipment
    Patent number: 12281585
    Abstract: A drain removal monitoring equipment for monitoring, in a steam turbine, drain removal performed by drawing a fluid outside at least one hollow stator vane including an internal space into the internal space via a slit formed in a surface of the stator vane includes: a gas-liquid separation device for separating the fluid drawn into the internal space into a liquid phase and a gas phase; a liquid-phase flow measurement device for measuring a flow rate of the liquid phase separated by the gas-liquid separation device; a gas-phase flow measurement device for measuring a flow rate of the gas phase separated by the gas-liquid separation device; a liquid-phase return line through which the liquid-phase flow measurement device and the steam turbine communicate with each other, and a gas-phase return line through which the gas-phase flow measurement device and the steam turbine communicate with each other.
    Type: Grant

  • Variable geometry turbocharger
    Patent number: 10385765
    Abstract: An object is to is to reduce a leakage flow by reducing a clearance between an end surface of a nozzle vane, forming a variable nozzle mechanism of a variable geometry turbocharger, and a wall surface facing the end surface, and prevent the nozzle vane from being stuck due to contact of the end surface.
