Definitions

the invention relates to a multi-part piston for internal combustion engines according to the preamble of the claim.
the object of the invention is to find a reliable and simple fixation within the piston parts to be connected for a sheet metal ring to be inserted for the isolation of certain partial areas, in which neither the material properties of the piston part in question nor its material properties due to the type of connection of the ring to be introduced can be negatively influenced.
a suitable type of connection can, for. B. can be achieved in that the ring to be introduced is attached to the intermediate ring with screws. The screws are then screwed in on the side of the intermediate ring which faces outwards as seen from the inside of the cooling oil duct.
FIG. 1 An embodiment is shown in the drawing, which shows a cooling oil channel in longitudinal section through a two-part piston.
a steel piston crown 1 is attached to an aluminum piston lower part 2 by fastening means, not shown. Cooling oil flows through the annular space 3.
a slotted flexible ring 5 is introduced to shield a partial area 4 of the annular space 3. This ring 5 is via screws 6 on an intermediate ring 7 from z. B. steel fit between the piston crown 1 and the lower piston part 2.
the parting line 8 of the slotted ring 5 can be welded subsequently.
the ring 5 is preformed in such a way that after its assembly, it rests firmly against the piston wall region to be covered at its upper free end.
