ABSTRACT:
The invention relates to a fluid clutch of the kind comprising cooperating vaned pump and turbine elements between which toroidal power-transmitting liquid vortices are established. At least part of the vanes of one of the elements is movable between clutch engaged and disengaged portions through a wall of the element into a reservoir on the other side of the wall. This reservoir also serves as a stall reservoir into which working liquid is fed automatically upon the existence of a stall condition of the element, so as to reduce the torque transmission capacity to a value preventing stalling of the prime mover.
