  • Piston with cast passages
    Patent number: 6152016
    Abstract: A piston is formed with one or more recesses or depressions on its underside as it is cast, molded or forged. The recesses are located adjacent the outer cylindrical wall of the piston head so that when a groove such as an oil ring groove is subsequently machined into the outer wall, the groove intersects and cuts into each recess. In this manner, oil drain ports are formed in the oil ring groove without the need for additional boring or cutting operations.
