| 主权项 | 1. A piston having a piston body and a number of piston rings and support rings which are arranged axially one behind the other on the piston body, wherein a piston ring and a support ring are arranged in a peripheral groove provided on the piston body, and the piston ring is supported on the support ring, wherein the axial width of the peripheral groove is greater than the total axial width of the support ring and of the piston ring, and the support ring defines a radially inwardly facing surface spaced a distance from a floor of the peripheral groove in which the support ring is located, and the support ring is an unbroken ring which is relief-milled from the piston body. | ||
