Coupling section of a pressurising agent conduit coupling

摘要

The coupling piece (4) comprises a coupling housing (12) and a tappet (14) fixed stationarily in the housing on one side and extending axially in direction of a front coupling side corresponding to a coupling axis (16) with an opposite free tappet end (14a). The tappet has a fluid channel (22) cropping out from a rear line connection (20) with a transverse opening (24) that is arranged in the area behind the free tappet end. A sleeve-like valve body (26) has a stop unit (32) in its rear area. The stop unit in closed position reaches inside the coupling housing in a limit stop position.
