摘要： A reusable liquid filtering system and a disposable liquid filter used in the liquid filtering system are provided for use with an internal combustion engine or pump. The liquid filter includes first and second end members and a liquid bypass valve is connected to and projects outwardly from the first end member whereby excessive oil pressure will result in opening of the bypass valve so that an emergency oil flow bypass is thereby provided. The disposable liquid filter is removably positioned within a container of the reusable liquid filtering system. A base is removably connected to the engine or pump and to an open end of the container for allowing removal and replacement of the liquid filter and for allowing neat and spill-free drainage of oil from the container when the base and the container have been removed from the engine or pump and when the base has been removed from the container.

摘要： A fluid filter assembly incorporates a filter element and valve assembly within a filter housing and base plate. The filter element and valve assembly is a single pre-assembled unit which includes an anti-drainback valve seat and diaphragm, a by-pass valve assembly, a pleated paper filter element, and a spring endcap. The filter housing and base plate separably clamp together to enclose the filter element/valve cartridge which is replaceable, as a single assembly, once its filtering ability is degraded. The anti-drainback valve seat engages complementary features on the base plate to correctly align and position the filter/valve cartridge during assembly. Further, a recess within the top of the filter housing receives a protrusion on the filter element endcap to provide additional alignment and to provide pressure to seal the filter/valve cartridge to the base plate in a fluid-tight manner.
摘要翻译：流体过滤器组件将过滤元件和阀组件结合在过滤器壳体和底板内。过滤元件和阀组件是单个预组装单元，其包括防回流阀座和隔膜，旁通阀组件，打褶纸过滤元件和弹簧端盖。过滤器壳体和基板可分离地夹紧在一起，以便过滤能力降低时将可更换的过滤元件/阀芯作为单个组件包围。防排水阀座接合底板上的互补特征，以在组装过程中正确对准和定位过滤器/阀芯。此外，过滤器壳体的顶部内的凹部容纳过滤器元件端盖上的突起，以提供额外的对准并且提供压力以将流体密封到过滤器/阀芯到底板。
