ABSTRACT:
A fluid clutch of the kind comprising cooperating radiallyvaned pump and turbine elements has at least a portion of each vane of one of the sets of vanes of the pump and turbine elements movable either by axial motion or by pivoting motion under an external operator's control within an external enclosure formed between the outside face of the respective element and an annular shell rotatable therewith. Disengagement of the clutch is effected by the said motion which withdraws the movable vanes or vane portions from the working circuit into the said external enclosure, so that the power transmitting vortices usually produced by the vanes cannot be maintained. The clutch turbine may be provided with a device which can apply some rotational friction thereto when the clutch is fully disengaged, in order to stop the turbine fully against residual fluid friction in the working circuit.
