There are only two types of systems that transmit energy hydraulically. 1 2 Hydrostatic Hydrodynamic

Hydrodynamic systems are based on the principle that a fluid in motion exerts power. The torque converter works onthe same principle as a hydraulic clutch, but it employs an additional element called a stator. With the stator, the converter can multiply the torque at a ratio of 1:3. If the torque of an engine is 100 kN, for example, the converter can multiply the torque to 300 kN through the stator.

2.3.2 BASIC DESIGN OF THE TORQUE CONVERTER The torqueconverter is a closed and sealed unit, filled with oil from the transmission. It transmits the rotational power from the engine to the transmission and can multiply the engine's torque to provide a smooth take-up of power without the need for foot-operated clutches. The torque converter consists of the following components:

The drive housing (8) driven by the engine is connected directly to the impeller (4) which transmits the engine's rotational power to the torque converter components. The turbine (6), which is the driven member of the torque converter, is connected to the transmission input shaft (7) and transmits the drive to the transmission...
