Abstract (en)
[origin: DE19747944A1] The invention relates to a piston (1) with a central cooling chamber (7). Said cooling chamber is located beneath the piston head and is impinged upon by oil. At least the lower wall of the cooling chamber (7) is formed by a plate (9). The aim of the invention is to provide a means of fixing the plate (9) to the piston (1) as easily as possible. To this end, the piston (1) has at least one second pin or clamping sleeve situated above the piston pin (14). Said second piston pin or clamping sleeve (13) has a smaller diameter, extends approximately in the direction of the piston pin axis and is connected to the piston (1). The plate (9) which forms the lower wall of the cooling chamber (7) is supported against the second piston pin or clamping sleeve.
