<p>A machine for generating motion is constructed like an epicyclic gear, with the intermediate gears mounted on a cylindrical core between the inner and outer gears. The intermediate gears are alternately axially offset and the core provides circumferential undulating guides for pistons that slide in the inner and outer gear teeth so that they pass over and under the intermediate gears. The pistons and intermediate gears divide the space between inner and outer gears into separate chambers to which pressure fluid can be selectively admitted to achieve rotation.</p> |
