ABSTRACT:
A fluid flow engine comprises a shaft supported in a bearing housing by means of a bearing shell. There are at least two lubricating bores in the bearing shell each having a predetermined geometry as to diameter, length and angular arrangement with respect to the bearing shell. At least one turbine rotor is on one end of the shaft. A turbine housing provides a turbine space for accommodating the turbine rotor, the turbine housing being connected to the bearing housing. There are sound suppressing means arranged within the bearing housing.
