图9-12显示了进一步的实施例，且为了便于理解在合适的地方使用了与上文相似的标记。图11中，过滤元件和壳体具有各自的边缘40和38，边缘40和38在已提到的匹配的交接面处相互匹配且沿着沿周界的延伸方向延伸。匹配的交接面具有沿着相对于周界的径向方向延伸的宽度。匹配的交接面具有沿着已提到的延伸方向延伸的长度。边缘具有在匹配的交接面处的面对的表面，包括在过滤元件上的第一面对的表面80和在壳体上的第二面对的表面82。图11中，第一和第二面对的表面中的至少一个沿长度沿着所提到的延伸方向非直线地延伸以提供带键的交接面。在优选实施例中，第一和第二面对的表面80和82均沿长度沿着所提到的延伸方向非直线地延伸以提供带键的交接面，而面对的表面中的一个，例如82，以嵌套的关系收纳另一个面对的表面，如80。在图9和11中，带键的交接面在横断于已提到的径向方向而截取的横截面上具有V形形状。在这类实施例中，第一和第二面对的表面80和82均具有在横断于已提到的径向方向而截取的已提到的横截面上的已提到的V形截面，而面对的表面中一个，例如82，其V形相对于交接面为凹面的V形，而面对的表面中的另一个，例如80，其V形相对于交接面为凸面的V形，凹面的V形的那个面对的表面以嵌套方式收纳凸面的V形的另一个面对的表面。在图10和12中，带键的交接面40a和38a在面对的表面80a和82a处，在横断于已提到的径向方向而截取的横截面上，具有弧形形状。在优选实施例中，第一和第二面对的表面80a和82a均具有在已提到的横断于已提到的径向方向而截取的横截面上的弧形形状，而面对的表面中一个，例如82a，其弧形形状相对于交接面为凹面的弧形形状，而面对的表面中的另一个，例如80a，其弧形形状相对于交接面为凸面的弧形形状，凹面的弧形形状的那个面对的表面以嵌套关系收纳凸面的弧形形状的另一个面对的表面。
图13示出了另一实施例，此实施例具有沿边缘的一个或多个安装销式***，例如81、83，以在一实施例中提供过滤元件和壳体的一个或多个的给定或特定的方向。在另一实施例中，一个或多个安装销式***提供了所述过滤元件在所述壳体内的单向配合。在另一实施例中，一个或多个安装销式***只提供经授权的替换过滤元件的更换。
在进一步的实施例中，过滤元件和壳体具有边缘40和38，边缘40和38在匹配的交接面的密封件处相互匹配且沿着沿周界的延伸方向延伸，从而限定了接合面，每个边缘和所述密封件在已提到的接合面上具有非对称的形状，如图14中的非对称形状88，或者其它的非非对称形状。在一实施例中，密封件由密封垫89提供，且密封件也具有非对称轮廓。在进一步的实施例中，密封垫89的非对称轮廓减小了壳体的体积。在一实施例中，边缘具有带有心形分段的一个部分，例如89处所示。过滤元件和壳体的边缘在接合面上互补，且结合非对称性，提供了过滤元件在壳体内的仅单向配合。在进一步的实施例中，过滤元件和壳体具有在匹配的交接面处彼此匹配的边缘，且边缘沿着沿周界的延伸方向延伸，从而限定了接合面，并且被配置为提供过滤元件在壳体内的仅单向配合。
此外在优选实施例中，提供了用于已提到的过滤密封***的替换过滤元件22，其中替换过滤元件包括已提到的带键的交接面。过滤元件包括带键的边缘以提供该带键的交接面。
此外在优选实施例中，提供了用于过滤器的过滤密封***，过滤器具有位于壳体内的过滤元件，壳体包括至少两个部分，过滤元件为第一构件，壳体部分包括第二和第三构件，其中已提到的构件中的至少两个在匹配的交接面处相接，而密封***即为具有带键的所述交接面。
本发明的优选实施例进一步提供了用于过滤器的过滤密封***，过滤器具有位于壳体中的过滤元件，所述壳体具有在图15中连接至流动导管90的壳体口36，流动导管90用于两者间的沿流动方向(图15中为向下)的流体流动。口36具有沿流动方向延伸的长度，和横断于此长度的宽度。口的宽度沿口的长度变化，优选提供用于装配入流动导管的导入部。口沿着沿长度的纵向轴线92纵向延伸且具有逐渐变细的侧壁94，侧壁94随着其纵向延伸而逐渐变细。逐渐变细的侧壁94提供了已提到的变化的宽度。口36沿逐渐变细的侧壁94截头圆锥形地逐渐变细。逐渐变细的侧壁具有一个或多个密封凸部96，密封凸部96与流动导管90以机械压力密封的关系相接合。导管90可以是具有弹性的可弯曲材料，例如橡胶，当它围绕侧壁94和密封凸部96并装在其上时可以伸展，或者导管90可以具有与侧壁94的截头圆锥形的锥状部互补的截头圆锥形的锥状部。
在进一步的实施例中，密封垫和壳体被配置成每次更换过滤元件时可以选择是否提供新的密封垫。在进一步的实施例中，密封垫和壳体被配置成每次更换过滤元件时必须提供新的密封垫。这样可以减少对密封垫在壳体内随着时间的推移产生压缩永久变形并且在与过滤元件连接时泄漏的担心。壳体可以配备用于收纳可替换密封垫的一个或多个卡扣配合的狭槽或沟槽。
在前文的描述中，为了简洁，明了及便于理解而使用了某些术语。由于这些术语是出于描述性目的且意在被宽广地进行解释，因此不含有超过现有技术需求的不必要的限制。此处描述的不同的构造，***及方法步骤可单独使用或与其他构造，***及方法步骤组合使用。将预期到的是在所附权利要求的范围内，各种等同物、替换物和修改物是可能的。
