Abstract
A continuous-flow machine (), in particular a turbine or a compressor, includes at least one stator blade section () which has a plurality of stator blades () which project into a gas path () of a working gas, and at least one adjacent section (), which has a plurality of adjacent elements (), which bound the working gas path () at the side. A gap (), through which a cooling gas can be introduced into the working gas path (), is formed between the stator blades () of the stator blade section () and the adjacent elements () of the adjacent section (). In order to improve the efficiency of the continuous-flow machine (), lateral seals () are formed in the gap () and prevent or at least impede pressure equalization and/or a gas flow in the gap () in the lateral direction ().
