is embodied of a randomly oriented pile of mineral fibers 12 naturally the principal construction of the gas guide element according to the invention according to fig1 to 5 is only intended to be an example gas guide elements are also possible which have both fewer than three convolutions and more than three convolutions the choice is made by one skilled in the art according to the main employment purpose of the gas guide element if this employment purpose is mainly directed toward reducing the sound intensity which exists at the gas entry 2 more than only three convolutions can easily be used the number of convolutions though is chosen so that not too increased a backpressure to the turbine 8 or to a different engine is produced by the pressure loss which increases with each convolution for this reason it is advantageous to enlarge for example to double the cross sectional faces of the gas guide conduit 16 of the inner hose 9 in relation to the cross sectional face of the main conduit 3 upstream of the gas inlet 2 for further reduction of sound intensity the inner hose 9 can also be provided with a spray device 15 according to fig2 in order to be able to inject water into the guide conduit 16 of the gas guide element 1 by means of which the thermal stress on the materials is also reduced a spray device 15.
