coupling element for a pressurized conduit coupling

摘要

The sleeve has an elastic ring seal (24) arranged in a circumferential sealing chamber (30) of a disk-like valve body (22) so that the seal is covered from front in a radial inner circumferential region by a front holding bar (32) of the body. The body includes an attachment section (34) in a region radially outwardly enclosing the seal for attachment within a coupling housing (18) as a mechanical end stop in a closing position. The body is integrally designed with the bar. The attachment section is formed by a separate ring element (36), which circumferentially encloses the seal.
