摘要
<p>The bilateral gas tight piston ring has a ring segment, in which opposite segment ends are provided, such that an end is formed as sliding bracket and the other end as T-profile. An inner sliding cavity of a certain width of the bracket-end (A) has an outer contraction of a certain width. The inner sliding pin of the T-profile-end (B) has an outer swelling of certain width.</p>
