20090250030 | Engine with desmodromically actuated rocker - An engine comprising a valve, cam lobe, rocker, follower member and an optional spring is disclosed herein. The valve may comprise a valve stem. The cam lobe may have a base circle and a nose. The cam lobe may be attached to a rotating shaft. The rocker may have a valve end portion contacting the valve, a lifter end portion defining a pivot axis of the rocker and a cam surface disposed between the valve end portion and the lifter end portion. The nose of the cam lobe may contact the cam surface for opening the valve. The follower member may be disposed adjacent the cam lobe opposite the rocker. The follower member may be attached to the rocker and have a curved inner surface upon which the nose of the cam lobe contacts for lifting the rocker. The spring may be disposed about the valve stem of the valve for closing the valve stem of the valve. | 10-08-2009 |

20090050083 | Engine with round lobe - An engine with intake and exhaust valves that may be controlled with a circular cam lobe is provided. The rotating axis of the circular cam lobe is offset from the physical center of the cam lobe. This permits the cam lobe to impart a reciprocal opening and closing of the valve. To maintain the valve in the closed position, the interconnection between the cam lobe and the valve | 02-26-2009 |
