Abstract (en)
[origin: US2004244581A1] A piston for an internal combustion engine which comprises a piston body, and a ring element, which together form a basic piston body. When the ring element is screwed onto the piston body, it forms a ring shaped cooling channel which is closed off in a direction of the pin bosses by a projection of the basic body. The projection is structured in the form of an elastically resilient cup spring which is deformed when the ring element is screwed onto the body. This deformation and counter stress, contributes to the strength of the screw connection.
