Abstract

A filter assembly (100) is provided. The filter assembly (100) includes a first component (102) having a first groove (114). The filter assembly (100) also includes a second component (104) having a second groove (114). The first groove (114) of the first component (102) and the second groove (114) of the second component (104) define a channel (138) therebetween. Additionally, the filter assembly (100) includes a cord member (140) that is removably inserted into the channel (138) to detachably couple the second component (104) to the first component (102) .

Description

technical field [0001] The present invention relates to a filter assembly for filtering fluid. Background technique [0002] Filter assemblies are known in the art for use in various applications, for example, internal combustion engines, hydraulic or pneumatic systems, and the like. These filter assemblies can be used to filter fluids in fuel systems, lube oil systems, hydraulic oil systems, air or exhaust filtration systems, and more. There are different types of filters such as cartridge filters, spin-in filters, etc. It is important to service such filter assemblies at regular intervals because the filter elements in these filter assemblies may tend to become clogged with impurities in the filtered fluid and may need to be replaced. [0003] US Patent 5,820,646 relates to a filter device inserted in a conduit with fluid passing from upstream to downstream. The filter device includes a grooved filter media having grooves formed therein. The filter forms a seal between...
