摘要： An apparatus for measuring the differential pressure of fluid in filter. The apparatus comprises a housing defining a pressure chamber. A differential pressure gauge divides the pressure chamber into first and second fluid chambers. The differential pressure gauge is arranged to measure a differential pressure between fluid in the first chamber and fluid in the second chamber. The differential pressure gauge has a variable output.

摘要： A fluid filter arrangement includes a housing defining a slot arrangement. A filter cartridge is oriented within the housing. A projection arrangement engages the slot arrangement in the housing and spaces the filter cartridge from a wall of the housing to define a fluid flow path between the cartridge and the housing wall. A filter cartridge includes a tubular construction of filter media and a projection arrangement. A filter assembly includes the filter arrangement connected to a filter head. Preferably, the filter cartridge and filter head are made of plastic. Methods of assembling a filter includes inserting a filter cartridge and projection arrangement into an open end of a housing, engaging projections against through-slots defined by the housing to secure the filter cartridge in the housing. In some arrangements, a filter housing includes a plastic wall having an interior side with a support structure in the form of ribs extending from the interior side of the housing. In some arrangements, the plastic filter head is modular and may include male threads molded as part of the filter head.

摘要翻译： 流体过滤器装置包括限定槽布置的壳体。 滤筒定位在壳体内。 突出装置接合壳体中的槽布置并且将滤筒与壳体的壁隔开，以限定在盒和壳体壁之间的流体流动路径。 滤筒包括过滤介质的管状结构和突出装置。 过滤器组件包括连接到过滤头的过滤器装置。 优选地，滤筒和过滤头由塑料制成。 组装过滤器的方法包括将过滤器滤芯和突出装置插入壳体的开口端，将突起抵靠由壳体限定的通孔，以将滤芯固定在壳体中。 在一些布置中，过滤器壳体包括具有内侧的塑料壁，其具有从壳体的内侧延伸的肋状形式的支撑结构。 在一些布置中，塑料过滤头是模块化的，并且可以包括作为过滤头的一部分模制的阳螺纹。
