摘要

A fluid flow engine comprises a guiding grid in a housing arrangement for housing a turbine wheel. The housing arrangement has a central discharge channel for the fluid driving the turbine wheel. A ring of guiding vanes located around a central axis is mounted to a support ring around the central axis. The support ring is inserted into the housing arrangement and is fastened in an axially and a radially moveable manner to the housing arrangement by a appropriate fastening device which enables such mobility.
