Patent Number: 8,821,105

Title: Turbine with variable number of nozzles

Abstract: The nozzles include inlet ports circumferentially arranged into a group and an opening and closing valve disposed so as to be commonly functioned. This arrangement realizes a gas turbine with no deterioration of efficiency against fluctuation of gas inflow rate by only one heat-resistant moving component additionally installed. The variable nozzle number turbine according to this invention also realizes a turbine compressor with no surge limit when used as a regenerator. These turbines further realizes a small-sized gas turbine with improved fuel economy under partial load conditions and a turbocharger for regenerating electric power as well as improving efficiency of a displacement engine.
