COOLING GALLERY FAN ASSEMBLY FOR A PISTON

摘要

A piston for an internal combustion engine defining an axis of motion and including an annular cooling gallery defined within the piston. The cooling gallery extends annularly about the axis of motion of the piston. A plurality of annularly spaced fan blades is positioned within the cooling gallery. Each fan blade is oriented diagonally within the cooling gallery to direct a cooling fluid in an annular direction about the axis of motion of the piston.
