System comprising a connector for coupling to a fluid filter element, fluid filter element, and process for producing same

The present disclosure is directed to a new quick-connect, bayonet-type coupling arrangement for use with connecting a filter cartridge or element to a fluid- consuming machine. Advantageously, the features of the coupling arrangement can be provided while simultaneously maintaining backward compatibility with screw- thread based systems by modifying the screw thread on the end cap so as to include judicially arranged non-interfering segments. Accordingly, the disclosed fluid filter elements can not only be installed on systems according to the present disclosure but also on prior-art systemspresenting a thread-based connector. 本披露内容涉及一种用于与将滤筒或滤芯连接到流体消耗机器一起使用的新的快速连接的卡口型联接布置。有利的是，通过修改端盖上的螺纹以便包括合理布置的无干扰节段，可以提供联接布置的特征，同时保持与基于螺丝螺纹的系统的向后兼容性。因此，所披露的流体滤芯不仅能够安装在根据本披露内容的系统上，而且还能够安装在具有基于螺纹的连接器的现有技术系统上。
