Abstract: The invention relates to a piston for an internal combustion engine, comprising an essentially cylindrical basis member made of forged aluminum and a ring element that is disposed in the radially outer edge area of the bottom of the piston and forms an annular cooling channel along with the basic member. The ring element is made of cast aluminum and is provided with a ring support for a compression ring, said ring support being made of Ni-resist.

Abstract: A one-piece piston for an internal combustion engine, having a ring-shaped cooling channel arranged in the outer region of the piston head, is proposed, which is closed off by a ring-shaped cooling channel cover structured towards the side of the pin bosses as a support element. This cooling channel cover comprises at least two arc-shaped cover elements the outer edge of which supports the pin-boss-side face of the ring wall.

Abstract: 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.
