Said guide wheel has inlet eyes arranged on the outside of the entrance edge of guide blades around the outer diameter of the impeller and axially extended up to an intermediate position between a wall adjacent to the impeller and a cover wall of the return portion of the guide ducts. Said guide blades are arranged around the outer diameter of the impeller without radial overlappings of the end portion of a guide blade with the initial portion of the subsequent guide blade. <IMAGE>
