The hydrodynamic principle of a fluid coupling makes it easy to gently accelerate driven machines. At the same time, fluid couplings limit torque, provide load. The fluid coupling consists of a pump impeller (on the input shaft) and a runner (on the output shaft). Both impellers are housed in the same casing. See Fig. Föttinger principle – the Föttinger coupling. Originally the operating principle of the fluid coupling is based on the hydrodynamic torque converter patented by.

The oil may be pumped back into fluid coupling coupling when needed, or some designs use a gravity feed - the scoop's action is enough to lift fluid into this holding tank, powered by the coupling's rotation.

Scoop control can be used for easily managed and stepless control of the transmission of very large torques. The Fell diesel locomotivea British experimental diesel railway locomotive of the s, used four engines and four couplings, each fluid coupling independent scoop control, to engage each engine in turn.

It is commonly used to provide variable speed drives.

Rail transportation[ edit ] Fluid couplings are found in some Diesel locomotives as part of the power transmission system. Self-Changing Gears made semi-automatic transmissions for British Rail, and Voith manufacture turbo-transmissions for railcars fluid coupling diesel fluid coupling units which contain various combinations of fluid couplings and torque converters.

As the fluid strikes the turbine blades it starts rotating.

With the increase in the speed of impeller, the velocity of the turbine increases and becomes approximately equal to the impeller speed. The fluid after passing through the turbine blades again fluid coupling to the impeller.

How Ignition Distributor Works? No fluid coupling can run at percent efficiency.

Excessive heat production from poorly maintained couplings can result in damage to the coupling and surrounding fluid coupling.

In accordance with the hydrodynamic affinity laws, the turbine speed is also dependent on the pump speed.

The fluid coupling has the same characteristics in both directions of rotation. These coupling have a sliding scoop tube which enters the coupling rotating fluid coupling through central clearance.

Fluid coupling oil quantity level in the coupling can be varied which in operation by changing the position of the scoop tube which determines the oil level in the coupling.
