Schnellkupplungsvorrichtung

摘要

A first quick-coupling part (1,2) can be brought into interaction with a second quick-coupling part (4) via an interaction portion (1). The quick-coupling parts are held together with locking members (5). The interaction portion (1) is designed with a surface layer for contact by the members (5) which brings about a crack-free flexibility for them in spite of high actuating forces. One or more underlying layer(s) has (have) greater hardness than the surface layer, and the combination of said layers gives the necessary resistance against high media pressure.
