    • A filter arrangement for threadably securing to a filter head includes a housing having a surrounding wall defining an interior volume, an open mouth providing access to the interior volume and an end opposite of the open mouth. The surrounding wall has an exterior and an interior. A filter media construction is operably held within the interior volume. A sleeve, distinct from the housing, is secured to the exterior of the surrounding wall adjacent to the housing mouth and extending partially along the surrounding wall. The sleeve has an exterior and an interior. The exterior of the sleeve defines mounting threads constructed and arranged to removable mount with the filter head, when the filter arrangement is secured to the filter head. The interior of the sleeve is against the exterior of the surrounding wall. A first seal member is oriented against the sleeve to create a seal with a filter head, when the filter arrangement is secured to the filter head. A filter assembly includes a filter arrangement and a filter head. The filter arrangement is removably secured to the filter head by a threaded connection between the sleeve and the filter head. A system includes an engine utilizing a liquid and a filter assembly in fluid communication with the engine to filter the liquid. Methods of making filter arrangements include utilizing structures characterized above.
    • 用于螺纹固定到过滤头上的过滤装置包括壳体,该壳体具有限定内部容积的周围壁,提供通向内部容积的开口以及与开口相对的端部。 周围的墙壁有外部和内部。 过滤介质结构可操作地保持在内部容积内。 与壳体不同的套筒被固定到与壳体口相邻的周围壁的外部并且部分地沿着周壁延伸。 袖子有外部和内部。 当过滤器装置固定到过滤器头部时,套筒的外部限定安装螺纹,该安装螺纹构造并布置成与过滤器头可拆卸地安装。 套筒的内部靠在周围墙壁的外部。 当过滤器装置固定到过滤器头部上时,第一密封构件定位成靠着套筒以与过滤器头部形成密封。 过滤器组件包括过滤器装置和过滤器头。 过滤器装置通过套筒和过滤器头之间的螺纹连接可拆卸地固定到过滤器头。 一种系统包括利用液体的发动机和与发动机流体连通以过滤液体的过滤器组件。 制造过滤器装置的方法包括利用上述特征的结构。

    • Exemplary embodiments and various aspects of the present invention are directed towards a pre-insulated control valve and a strainer of a piping system and a method of pre-insulating a control valve and a strainer. The method involves providing at least one a rigid polymeric foam, casting an insulation layer having a predetermining thickness from the polymeric foam designed to reduce thermal conduction between the valve or the strainer and the surface coming in contact with the valve or the strainer, coupling the control valve or the strainer with the insulation layer to provide a pre-insulated control valve or a pre insulated strainer and engaging the pre-insulated control valve or the pre insulated strainer in the fluid distribution system at multiple predetermined locations.
    • 本发明的示例性实施例和各个方面涉及管道系统的预绝缘控制阀和过滤器以及预控制阀和过滤器的绝缘方法。 该方法包括提供至少一个刚性聚合物泡沫,从聚合物泡沫铸造具有预定厚度的绝缘层,其设计成减小阀或过滤器与与阀门或过滤器接触的表面之间的热传导, 控制阀或具有绝缘层的过滤器,以提供预绝缘控制阀或预绝缘过滤器,并且在多个预定位置处与流体分配系统中的预绝缘控制阀或预绝缘过滤器接合。
