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.

Axial torque governor for a turbo-supercharger for internal combustion

An exhaust gas turbocharger comprising a bearing sleeve (26) for radially bearingly mounting a shaft (14), which sleeve is arranged in a bore (36) of a bearing housing (6) and is secured against rotation. The sleeve (26) has an inner bearing surface (34) and an outer jacket surface (32) at each of its two axial end regions, whereby lubricant present in the gap between the sleeve (26) and the bore (36) achieves a damping effect. With a thin shaft and at high rotational speeds, the exhaust gas turbocharger should have a high degree of functional reliability. It is proposed that the sleeve (26) be subdivided into two axially spaced bearing bushings (20, 22) which are connected to each other by small and substantially rigidly formed bridges (24). The securing devices comprise a rod (46) which lies in contact with one of the bridges (24) and serves only to prevent rotation of the sleeve (26) which otherwise can carry out free floating movements.
