Abstract
A fluid-operated transmission device has an impeller mounted within an input chamber which is driven by a motor or other motive source. A variable-speed rotor is positioned within an output chamber, the volume of which is selectively adjustable by positioning of a baffle means so that the volume of the output chamber which forms part of the fluid flow circuit may be selectively adjusted, thereby adjusting the speed of hydraulic fluid passing through the output chamber, and thereby the speed of the output rotor at constant output power. Fluid flow direction means are provided which enable braking and/or reversing direction of rotation of the variable-speed rotor by changing the direction of flow of the fluid impinging onto the impingement surface thereof.
