The bulkhead is made as a unit with the piston and reinforced by a plate of a strong material during the piston casting; the strong material ring is mounted on the end of the piston partition and embraces said partition.
A bulkhead, being a part of a big sphere of the piston, is made on the piston partition, on the flank of said side walls from the big sphere of the piston to the piston skirt side.
The bulkhead and side walls, during a piston blank casting, are reinforced with strong material in the form of a thin plate, mounted along the piston partition and connecting side walls.
