The stator (reaction member) following the turbine, has the task to reverse the oil, which is
streaming out of the turbine once more and to deliver it under the suitable discharge direction
to the impeller.
Due to the reversion, the stator is receiving a reaction torque.
The relation turbine torque/pump torque is called torque multiplication. This is the higher, the
greater the speed difference of impeller and turbine wheel will be.
Therefore, the maximum torque multiplication is created at stationary turbine wheel.
With increasing output speed, the torque multiplication is decreasing. The adaption of the
output speed to a certain required output torque will be infinitely variable and automatically
achieved by the torque converter.
When the turbine speed is reaching about 80% of the pump speed, the torque multiplication
becomes 1,0 i.e. the turbine torque becomes equal to that of the pump torque.
From this point on, the converter is working similar to a fluid clutch.
A stator freewheel serves to improve the efficiency in the upper driving range, in the torque
multiplication range it is backing-up the torque upon the housing, and is released in the clutch
range.
In this way, the stator can rotate freely.
