ABSTRACT:
A disengageable connection between an internal combustion engine and a propeller which serves for the drive of a gyroplane. The disengageable connection is a fluid coupling which includes a controllable oil circulatory system. The fluid coupling is supplied with oil by way of the oil circulatory system during the operation of the internal combustion engine. By contrast, the oil escapes out of the fluid coupling when the propeller operates under auto-rotation.
