Torque converter is a type of fluid coupling that uses a fluid to transmit turning effort from the one shaft to another. It is a device which performs a function similar to that of a gear box, namely, to increase the torque while reducing the speed. A gear box provides only a small number of fixed ratios, but the torque converter provides a continuous variation of ratio from the lowest to the highest.The torque convertor is somewhat similar to a fluid fly wheel, but differs from it in one aspect, namely it has three principal components instead of only two. Torque converter consists of (i)  The driving element or impeller or pump which is connected to the engine. (ii)  The driven element or rotor or turbine which is connected to the propeller shaft and (iii)  The fixed element or reaction member or stator which is fixed to the frame. The fixed element is responsible to cause a change of torque between input and output shafts. The fluid flywheel does not ...
