Clutch part of a pressure medium line coupling and valve body for a coupling member
2011
Coupling part (2) of a pressure medium line coupling (1) consisting of two matable and automatically mutually open during mating closing valves (6, 8) having coupling parts (2, 4), wherein the closing valve (6) comprises in a clutch housing (18) comprising such according to a coupling shaft (20) axially movably guided valve body (22) that this automatically from a closed position counter to a closing spring force in the clutch housing (18) into an open position is moved during the coupling process by bearing against the other coupling part (4), wherein having the valve body (22) forward in his, pointing in the closing direction of the peripheral region a resilient ring seal (24) cooperating enclosing the axial seal with a front housing opening (26) sealing surface (28) of the coupling housing (18), wherein the annular seal (24) Derar in a circumferential proper seal chamber (30) of the valve body (22) t is arranged so that it is covered in its radially inner circumferential portion of the front of a retaining web (32) of the valve body (22) and forwardly in its radially outer peripheral portion for engagement with the sealing surface (28) is exposed, wherein the valve body (22) in the annular seal (24) radially outer region surrounding an abutment portion (34) for engagement within the clutch housing (18) as a mechanical end stop in the closed position, characterized in that is formed of the valve body (22) integral with the front lock bar (32) wherein the bearing portion (34) of a separate, annular seal (24) circumferentially surrounding ring element (36) is formed.
