GAS TURBINE COOLING FLOW REGULATOR Russian patent published in 2006 - IPC F02C7/12 F01D5/08 

FIELD: mechanical engineering; gas turbines.

SUBSTANCE: gas turbine cooling flow regulator contains compressor, great number of replaceable nozzles, guide tube and wrench with magnetic head. Compressor has inner hollow cylinder with cylindrical shell and great number of holes in cylindrical shell of inner hollow cylinder communicating with air compressor. Air delivered by compressor passes through holes in cylindrical shell into inner hollow cylinder. Replaceable nozzles have different-diameter channels, as compared with each other, and they are made for fitting in said holes to provide selective regulation of air flow delivered by compressor and passing into inner hollow cylinder. Selective regulation is provided by choosing and replacing at least some nozzles by other nozzle differing in inner channel of corresponding diameter. Compressor has outer housing through hole in which guide tube is fitted. Nozzles are installed through holding and guide channel for threaded connection with holes in shell of inner hollow cylinder. Holding and guide channel is formed by guide tube turned into hole of housing and provided with far end for connection with shell of inner hollow cylinder.

EFFECT: possibility to regulate flow of air getting into inner hollow cylinder without its replacement.
