2) OPERATION
The torque converter is working according to the Trilok-system, i.e. it assumes at high turbine speed
the characteristics, and therefore the favorable efficiency of a hydraulic clutch.
The converter will be defined according to the engine power so that the most favorable operating
conditions for each installation case are given.
The Torque converter is composed of 3 main components :
Pump wheel - turbine wheel - stator(Reaction member)
These 3 impeller wheels are arranged in such a ring-shaped system that the fluid passes through
the circulating components in the indicated order.
Pressure oil is constantly pressing out of the transmission pump through the converter. In this way,
the converter can fulfill its task to multiply the torque of the engine, and at the same time, the heat
created in the converter is absorbed through the escaping oil.
The oil, escaping out of the pump wheel, enters the turbine wheel and where the direction of flow is
inversed.
