PROPELLER TURBINE INSERTABLE INTO A LIQUID TRANSPORTING PIPELINE

摘要

The invention relates to a propeller turbine which is insertable into a fluid transporting pipeline and is provided with a speed controller incorporated therein. The inventive turbine comprises a preformed sleeve (20) whose central cylindrical part forms a channel comprising a freely rotatable propeller and which forms a chamber (28) which is connectable to an upstream pressure port (27a) and to a downstream pressure port (27b) by means of a connection (27c) and a valve (26) in such a way that the sleeve is more or less expandable by the liquid pressure.
