Abstract: The invention relates to a piston with a central cooling chamber. The cooling chamber is located beneath the piston head and is impinged upon by oil. At least the lower wall of the cooling chamber is formed by a plate. The purpose of the invention is to provide a means of fixing the plate to the piston as easily as possible. To this end, the piston has at least one second pin or clamping sleeve situated above the piston pin. The second piston pin or clamping sleeve has a smaller diameter, extends approximately in the direction of the piston pin axis, and is connected to the piston. The plate which forms the lower wall of the cooling chamber is supported against the second piston pin or clamping sleeve.

Abstract: A mushroom-type pin retainer for a pin having a central bore and which connects a piston and a piston rod of an internal combustion engine. The pin retainer is comprised of a mushroom head connected to a shaft. The shaft has a section of larger diameter for insertion into the bore of the pin. This section is no longer than 2 mm in an axial direction and is located remote from the mushroom head, so that the pin retainer may swing by a limited angle during mounting in the bore. This configuration makes the assembly simple to mount, even if it is manufactured by an imprecise manufacturing process such as injection molding.
