Technician A says when the coupling phase of the torque converter occurs and no torque multiplication takes place, there is little vortex flow and the engine's torque is carried through the converter by rotary flow of fluid. Technician B says when the speed of the turbine nearly equals the speed of the impeller, the fluid flows against the stator vanes in the same direction as the fluid from the impeller. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Question

Quizplus · Accepted Answer

Both technicians are correct. When the coupling phase of the torque converter occurs with no torque multiplication, the fluid flow is mainly rotary and there is little vortex flow. And when the turbine speed almost equals the impeller speed, the stator vanes direct the fluid flow in the same direction as the fluid from the impeller, increasing the efficiency of the converter.
