An important characteristic of a fluid coupling is its stall speed.

The friction clutch and the fluid coupling are the two basic varieties.

Hence a fluid coupling cannot achieve 100 percent power transmission efficiency.

The supercharger used fluid coupling for the second stage.

When a car is accelerating, fluid couplings can boost engine torque.

A type of fluid coupling, hydraulically connecting the engine to the transmission.

The motors and gear are coupled by fluid coupling.

Fluid couplings are found in some Diesel locomotives as part of the power transmission system.

It was a special manual transmission with a torque converter or fluid coupling.

His patents from 1905 covered both fluid couplings and torque converters.

The engine and transmission are connected by a fluid coupling called a torque converter.

The gearboxes were used in conjunction with a fluid coupling so no clutch pedal was needed.

Pressing the accelerator would move you forward, in third, with the fluid coupling connecting the engine to the transmission.

Fluid couplings are relatively simple components to produce.

Under stall conditions all of the engine's power would be dissipated in the fluid coupling as heat, possibly leading to damage.

When a fluid coupling is used for braking it is also known as a retarder.

The company also began development of high-performance fluid couplings, which were marketed under the Cupla brand name.

The main difference was the addition of a fluid coupling between engine and clutch, and the shifting mechanism.

As a fluid coupling operates kinetically, low viscosity fluids are preferred.

An alternative is to use a torque converter or fluid coupling in a direct drive system to replace the gearbox.

These turbines added power to the engine crankshaft through bevel gears and fluid couplings.

The receiver is stationary and so fluid couplings are not required (as in troughs and dishes).

This feature put a fluid coupling in between the engine and the clutch, although the driver still had to shift gears manually.

Parallel to the development in the 1930s of an automatically shifting gearbox was Chrysler's work on adapting the fluid coupling to automotive use.

The fluid coupling now only handled about 25 percent of the engine torque, reducing slippage to a negligible amount.
