    • The present invention relates in general to a fluid filter incorporating a plastic shell and a replaceable fluid filter cartridge. More specifically, the present invention relates to configuring the shell so that it will only accept, in terms of proper functioning, a cooperatively-configured replaceable fluid filter cartridge. One of the emerging technologies in terms of fluid filter construction is the enlargement of the threaded connection interface between the molded plastic shell and the fluid-delivery head, accompanied by the elimination of the typical or traditional nutplate. In one embodiment of this design concept, the shell is molded out of plastic and the outer cylindrical surface of the shell adjacent the open end of the shell is externally threaded. This threaded surface of the shell is used to attach the shell, and in turn the fluid filter assembly, to the head. This style of shell is configured for use with a spin-on style of filtration system as part of a disposable fluid filter assembly. Some end users of the type of filtration systems described above enjoy the advantages gained from a replaceable fluid filter cartridge. Therefore, it would be an advance in the state of the art to configure the molded plastic shell, generally as described above, but configured to accept a replaceable fluid filter cartridge. Related to the acceptance of a replaceable cartridge is the inability of the shell to accept a spin-on style of filter as part of a disposable, single-use system. The fluid filter construction disclosed herein is directed to providing this capability by the design of a novel and unobvious fluid filter endplate with cooperative modifications to the upper exposed edge of the shell that defines the open end of the shell.
    • 本发明一般涉及一种结合有塑料外壳和可更换流体过滤器滤芯的流体过滤器。 更具体地,本发明涉及配置壳体,使得其仅在正常功能方面接受协作配置的可更换流体过滤器滤芯。 在流体过滤器结构方面,新兴技术之一是扩大模制塑料外壳和流体输送头之间的螺纹连接界面,同时消除了典型或传统的螺母板。 在该设计概念的一个实施例中,外壳由塑料模制而成,外壳的与外壳的开口端相邻的外圆柱形表面是外螺纹的。 外壳的螺纹表面用于将外壳连接到流体过滤器组件上。 这种风格的外壳配置为与过滤系统的旋转式一起使用,作为一次性流体过滤器组件的一部分。 上述过滤系统类型的一些最终用户享有从可更换的流体过滤器滤芯获得的优点。 因此,通常如上所述配置模制塑料外壳,但是被配置为接受可替换的流体过滤器滤芯,在现有技术中将是先进的。 与可接受的墨盒的接受有关的是,壳体无法接受旋转式过滤器,作为一次性使用的一次性系统的一部分。 本文公开的流体过滤器结构旨在通过设计一种新颖且非显而易见的流体过滤器端板来提供该能力,其具有对限定壳体的开口端的外壳的上露出边缘的协调修改。
