Embodiment Construction

[0018] refer to figure 1 , the illustrated filter assembly 10 includes a filter housing 12, filter media 14 disposed within the filter housing, and a nut plate 15 attached to the open end of the filter housing. figure 1 The filter assembly 10 illustrated in is configured as a fuel filter assembly for filtering diesel fuel. However, filter assembly 10 may be configured for any desired filtration application. Examples of other filtration applications include, but are not limited to, petroleum filter assemblies for filtering petroleum, hydraulic filter assemblies for filtering hydraulic fluid, and other applications.

[0019] also, figure 1 The filter assembly 10 illustrated in is configured for single use. However, in other embodiments, the filter assembly may be configured to allow replacement of the filter media 14, in which case the housing 12 may be reused, and a removable cover may be attached to the filter housing. end (rather than the nut plate 15) to allow access to ...

Abstract

A filter housing that includes a bowl formed with a single thread that is stamped directly into the housing around a port. The thread is used to connect an auxiliary element, such as a drain valve or a WIF sensor, to the filter housing. An elevated ridge is formed around the bowl during the stamping process which increases the structural integrity of the housing around the port, and provides a surface for matching with the inserted auxiliary element.

Description

technical field [0001] The present disclosure describes a filter housing and a filter assembly using the filter housing, wherein the filter housing includes a single turn thread on a discharge port or a sensor port. Background technique [0002] In current filters, auxiliary elements such as water-in-fuel (WIF) sensors and / or drain valves are connected to the filter housing via crimp nuts. A corrugated nut is placed within the port in the filter housing, coated with a sealant, and corrugated to secure the corrugated nut to the filter housing. The auxiliary element is then screwed into the bellows nut, wherein a seal is provided between the auxiliary element and the bellows nut to prevent fluid leakage. However, fluid leakage may occur through the corrugated nut crevices. Furthermore, the corrugated nut brings additional cost and it requires a separate threaded component to be attached by an additional process. [0003] FR2880562 discloses a filter housing which eliminates...
