and the reactor 3. In the turbine wheel. 2, the hydraulic energy is converted into mechanical energy of the output shaft 16. The energy losses in the working torque converter are made up of various losses, including friction losses on the blades 10, 11 and 12, shock losses on

of the hydrotransformer, the meridional entrance edges 4, 5, and 6 of the blades 10, is a cross section.

The torque converter contains mounted, centrifugal turbine wheels 1, 2 and reactor 3, respectively, installed in series along the flow with a gap S, S, S between the input and output edges 4, 5, 6 and 7, 8, 9 blades 10, 11 and 12 on average line 13 current a and forming in the meridional section. a circular circle 14 of elongated shape, the ratio of the gap S between the output edges 8 of the blades 11 of the turbine wheel 2 and the input edges 6 of the blades 12 of the reactor 3 along the middle line 13 of the current to the active diameter H d of the torque converter is in the gap S. S and Sj. Experimental studies have shown that with the traditional execution of a torque converter with large 5 gaps S. and S, comparable with the lengths of the average lines of the blades 10, 11 and 12 in the meridional section, the losses in these gaps. S. and S on a number of operating modes of the torque converter are decisive. In this design of the torque converter, these losses are minimized.
