  • Heavy duty piston having oil splash deflector and method of cooling a piston
    Patent number: 6371061
    Abstract: A piston assembly includes a piston head having an open bottom cooling gallery and a pair of pin bosses depending from the head and supporting a wrist pin of a connecting rod. A skirt is coupled to the pin bosses for reciprocation with the piston head. A stationary oil spray nozzle extends into the piston skirt from below and cooperates with an oil splash deflector which, at a lowered position of the piston head, directs the flow of oil onto the pin bosses for direct cooling, and at raised position of the piston head, moves out of the way to allow the cooling oil to enter the cooling gallery and cool the piston head.
