Abstract: A housing (1) for a fluid flow engine comprises a first rotor space (2) for receiving and housing a turbine rotor, a bearing space (4) to house a shaft (5) of said turbine rotor, and a second rotor space (3) for receiving and housing a compressor rotor. The housing portions, which surround the bearing space (4), are integrally formed at least in part with those portions that surround at least one of the rotor spaces (2,3).

Abstract: An axial torque governor for a turbo-supercharger for internal combustion engines has a flow channel which is composed of a cylindrical section and of a spherical section following thereupon, the spherical section merging into a second cylindrical section by way of a nozzle section. The radius of the spherical section is equal to the radius of the first cylindrical section. A plurality of guide vanes are each composed of essentially circular segments which cover the cross-section of the first cylindrical section given complete closure of the inlet passage, whereby the pivoting axes of the guide vanes respectively lie in the entry edge of the vanes.
