ABSTRACT:
A valve rotator for a valve in an internal combustion engine. The rotator has a body and a cap which surround the valve stem and are movable toward and away from each other. Coacting with the cap and the body are a spring washer for transferring axial load from the cap to the body, and a shiftable element or elements carried in one or more pockets in the body and in contact with the spring washer. A fulcrum is provided for shifting the load from the shiftable element directly to the body whereby the shiftable element is reset for effecting rotation when the load on the spring washer is reapplied to the shiftable element.
The technical advantage of the present invention is that a much simpler, less expensive structure capable of smaller axial dimension than prior commercial structures is provided for a rotator operable on the valve closing stroke.
