Fluid coupling is a hydrodynamic device used to transmit rotating mechanical power. It has widespread application in marine and industrial machine drives, where variable speed operation and controlled start-up without shock loading of the power transmission system is essential.
A fluid coupling consists of three components, plus the hydraulic fluid. The housing, also known as the shell (which must have an oil-tight seal around the drive shafts), contains the fluid and turbines. Two turbines (fan like components), One connected to the input shaft known as the pump or impellor, and the other connected to the output shaft, known as the turbine, output turbine. The driving turbine is rotated by the prime mover. The impellor's motion imparts both outwards linear and rotational motion to the fluid.
The hydraulic fluid is directed by the 'pump' whose shape forces the flow in the direction of the output turbine, thus causing it to rotate in the same direction as the pump.Thus the power is transmitted from the driving to the driven
