ABSTRACT:
A piston (10) comprises a piston shaft (16) and an essentially cylindrical upper region (14). The piston shaft (16) essentially comprises two opposite shaft wall portions (16) relative to the pin axis. Two pin hubs (24) are also set back relative to the piston axis in the direction of the diameter of the piston shaft (16). On the piston are formed two communicating walls (18) which connect the shaft wall portions (16), which are also set back, which extend as far as the lower edge of the essentially cylindrical region (14) and in which the pin hubs (24) are located. According to the invention, the shaft wall portions (16) are provided in a largely concurrent manner with a dimension in the circumferential direction, this dimension varying in the direction of the piston axis. The communicating walls (18) also follow the thereby determined course of the edges of the two shaft wall portions (16), with these edges extending in the direction of the piston axis.
