torque converter

torque converter
quite similar to the fluid coupling that transfers engine torque to the transmissioninput shaft. It also cushions the flow of power. Unlike the fluid coupling the torque converter can multiply engine torque. This is accomplished by installing one or more stators between the torus members. In the torque converter the driving torus is referred to as the "pump" and the driven torus as the "turbine." The engine drives the impeller which in turn impels fluid against the vanes of a turbine connected through transmission gears to the driveshaft of the automobile. The stator redirects oil flow from the turbine to boost impeller action and multiply engine torque.
