Japanese Patent JPS5924289
Kind Code:
B2
Abstract:
A rotating fluid coupling of the type which has a primary coupling half and a secondary coupling half which together form a working chamber which is filled with working fluid. A control device which is arranged on the secondary coupling half is used to regulate the rotary take-off drive speed of the coupling by comparing an operating value, such as the centrifugal force which is a result of the rotating drive speed, with a variable command value and when the operating value differs from the command value initiates adjustment of the rotary drive speed. A fluid container on the secondary coupling half revolves with the secondary coupling half. A stationary supply line for control fluid to the fluid container is provided with a permanent outlet opening at a distance from the axis of rotation of the fluid coupling. A control piston is provided, the operating surface of which is spaced from the inner surface of the centrifugally driven fluid surface by a distance which locates the operating surface approximately at the permanent outlet opening. The control is thus independent of the rotary speed of the coupling. Some slight drift may occur during a change in speed until the forces balance out, but such variation in control is only momentary and the drifting is thus minimal.
