Technical Field

The present invention generally relates to filter assemblies for filtering fluid in an internal combustion engine system.

Background

Fluid filter elements are used in protection systems for engines. Such filter elements are used for fluid filtration, including, for example, filtration of oil, fuel, coolant, air, exhaust fluids, hydraulic fluids, crankcase ventilation and condensate, and intake air. For example, internal combustion engines typically combust a mixture of fuel (e.g., gasoline, diesel, natural gas, etc.) and air. Prior to entering the engine, the fluid (e.g., fuel, oil, and air) typically passes through a filter element to remove contaminants (e.g., particulates, dust, water, etc.) from the fluid prior to delivery to the engine.

The flow configuration into and out of the fluid filter element may be modified to reduce the level of restriction of the flow configuration into and out of the fluid filter element.

SUMMARY

According to a first set of embodiments, a filter assembly includes a housing. The housing comprises a first housing for the fluid and a second housing opening for the fluid. A containment cover is removably coupled to the housing. The closure cap defines a cap opening, a cap surface, and a flow channel. The cover opening is in fluid communication with the housing. The lid surface is substantially continuous around the circumference of the closure lid. The cover surface includes an open portion (open port) in fluid communication with the second housing opening. The flow channel is formed by a first channel surface and a second channel surface. The flow channel includes a first end in fluid communication with the cap opening. The second end is in fluid communication with the second housing opening through the open portion of the cover surface. The flow passage extends radially outward from the cap opening.
