Coupling part for pressure medium-pipe line coupling, has one of two intermateable and automatically opening mutually closing valve with coupling units having pressure fluid line coupling

摘要

The coupling part has one of two intermateable and automatically opening mutually closing valve (6) with coupling units having pressure fluid line coupling. The former closing valve has a valve body (22) that is movably guided in a coupling housing (18) according to a coupling axis. The valve body is integrally formed with a front holding bar (32) and an outer contact section (34) such that it formed from a pre-assembly, in which a mounting opening is sufficient for insertion of a ring seal (24) in a sealing chamber (30) in a final assembly position.
