Title:
MULTISTAGE TURBOMACHINE (VARIANTS)
Document Type and Number:
WIPO Patent Application WO/2013/184042
Kind Code:
A3
Abstract:
The multistage turbine comprises a housing, within which a working wheel with a bladed impeller is installed on a shaft. At the input opening end of the inter-blade channels, the impeller is adjacent to a distributor, with a gap therebetween. The distributor contains apertures and is capable of periodically aligning the input openings of the inter-blade channels of the impeller during the rotation thereof with an input pipeline and with a connecting pipeline for the supply of a working medium. At the output opening end of the inter-blade channels, the impeller is adjacent to a gas distribution apparatus, with a gap therebetween, said gas distribution apparatus containing apertures and being capable of periodically aligning said apertures with the output openings of the impeller during the rotation thereof. The apertures of the gas distribution apparatus are designed so as to form stages of discharge or expansion of the working medium. The aim of the invention is a simplified design, a smaller size and higher efficiency.
