DICHTUNGSRING

摘要

The invention concerns a seal ring, especially for use in automatic transmissions. In order to provide a seal ring which tends less to leakage than known seal rings, the invention proposes that the seal ring is free from ejector pin traces on the sealing surface. The invention provides seal rings with improved sealability and pressure stability. When used in automatic transmissions, these seal rings improve the drivability and better pressure stability during the shifting.
