FLUID COUPLING WITH SPEED-LIMIT DEVICE AND COMPOSITE TURBO-SYSTEM Russian patent published in 2009 - IPC F16D33/06 F02B37/04 

FIELD: machine building.

SUBSTANCE: invention elates to fluid couplings, particularly to composite turbo-system. Fluid coupling contains driving torus, turbine wheel and mechanical interlocking device. Turbine wheel together with driving torus forms filled by working liquid working area. Interlocking device is provided for connection without barring of driving torus and turbine wheel in case, if degree of filling of working area is lower than pre-defined value. Interlocking device can contain pin or lever.

EFFECT: providing automatic protection against rotating frequency increasing without usage of external power.
