Filter assembly with modular relief valve interface

摘要

A fluid filter assembly for filtering a fluid includes a housing base portion having an axially extending tube, a housing cover that is connected to the housing base portion to define an interior space, a filter element, and an interface structure. The filter element is disposed within the interior space and in engagement with the axially extending tube, the filter element having a filter media, a bottom end cap, a top end cap, and a mounting member defined by the top end cap, the mounting member having an axial wall with a vent passage therethrough and a radial wall that encircles the axial wall. The interface structure is connected to the housing cover and engages the top end cap of the filter element.

1. A fluid filter assembly for filtering a fluid, comprising:
a housing base portion having an axially extending tube; a housing cover, wherein the housing cover is connected to the housing base portion to define an interior space; a filter element disposed within the interior space and in engagement with the axially extending tube, the filter element having a filter media, a bottom end cap connected to the filter media, a top end cap connected to the filter media, and a mounting member defined by the top end cap, the mounting member having an axial wall with a vent passage therethrough and a radial wall that encircles the vent passage; and an interface structure that is connected to the housing cover and serves as an interface between the interior space and the filter element, the interface structure having an annular engaging part that defines a central opening, wherein the interface structure engages the top end cap of the filter element such that the vent passage of the mounting member is disposed within the central opening of the interface structure to create a fluid communication channel between the central opening, the vent passage, and the axially extending tube.
