Abstract
A device is described for transmitting mechanical power that allows variable output-speed to input-speed ratios. Gear sets such as epicyclic gear sets have components that rotate about a common axis selectively at the same rotational speed and at different relative rotational speeds as determined by at least one of fluid flow and fluid pressure. One or more inlet ports and fluid passageways introduce a working fluid into one or more volume spaces between the components. The internal pressure and flow of the working fluid through the device is controlled to provide substantially infinite variability of the output-speed to input-speed ratios for applications where, for example, an engine provides the mechanical power for propelling a vehicle.
