Abstract
A valvetrain for translating force and oil between a valve and intermediate member of an engine, including a rocker, a shaft, and a recess. The rocker has an inner surface, a pad for engaging the valve, a socket for engaging the intermediate member, a socket port defined in the surface, and a socket channel extending from the socket port to the socket. The shaft has a bearing surface for supporting the rocker, a channel spaced from the bearing surface, a feed port in the bearing surface, and a feed channel extending from the feed port to the channel. The rocker rotates between: closed, with the socket port and feed port aligned; and open, with the socket port spaced from the feed port. A recess is disposed in the bearing surface adjacent to the feed port and extends to a base aligned with the socket port when the rocker is open.
