Embodiment Construction

[0014] Various exemplary embodiments provide a filter assembly having a self-regulating air management device capable of automatically managing and adjusting based on the fluid or liquid level present within the filter assembly The amount of air introduced into a fluid or liquid filtered through a filter assembly. In certain embodiments, the self-regulating air management device can passively draw air present within the filter assembly to provide an adjustable amount of metered air to the filtered fuel and reduce unwanted noise in the downstream fuel pump risks of.

[0015] figure 1 is a filter assembly 10 with a self-adjusting air management device according to an exemplary embodiment. The filter assembly 10 generally includes a housing or housing 20 having a hollow interior space 22 and a lid or cover 30 removably connected to the housing 20 by, for example, external threads 31 which are in contact with the housing 20. The internal thread 21 on the periphery of the housin...

Abstract

An air management device for a filter assembly includes a top portion, a bottom portion, a plurality of frame members that connect the top portion to the bottom portion so as to define an inner cavity, and an air management valve. The air management valve includes a base portion, an intake valve, and an exhaust valve. The base portion is provided at the bottom portion. The intake valve extends into the inner cavity from the base portion towards the top portion. The intake valve includes an elongated opening that extends along a longitudinal length of the intake valve. The exhaust valve extendsinto the inner cavity from the base portion towards the top portion. The intake valve is configured to intake air through the elongated opening and the amount of air introduced through the elongatedopening varies based on a fluid level present within the air management device.

Description

technical field [0001] This application relates generally to fluid filtration systems, and more particularly, this application relates to fuel filter assemblies. Background technique [0002] In motor vehicles, fuel filters are often provided to clean the fuel before it is introduced into the engine to improve performance and extend the life of the engine. In some cases, an air management device may be provided within the filter element or cartridge to extract or manage the amount of air present within the fuel filter. In some applications, such as diesel engine applications, air management devices can also be used to mix metered air into the fuel prior to introduction into the engine for optimal combustion. [0003] Some air management devices incorporate the use of passive air management valves, which may include a fixed diameter orifice provided at the end of a tube or pipe extending into the filter element. Air present within the filter element is drawn through the ori...
