A filter assembly for filtering contaminants from liquid. A housing has a filtering chamber and an inlet port and an outlet port communicating with the chamber for flow of liquid therethrough. Filter media is located in the filtering chamber for filtering contaminants from liquid flowing through the filter media to the outlet port. A sump region is provided in the filtering chamber at the bottom thereof below the inlet port. Contaminants in the liquid entering the chamber from the inlet port tend to gravitate toward the sump region for collection. A separator member is located in the filtering chamber below the inlet port. This separator member substantially separates the filter media and sump region, and gravitating contaminants gravitate from the inlet port to the separator member. The separator member provides for communication of the gravitated contaminants into the sump region but tends to trap those contaminants in the sump region.

DETAILED DESCRIPTION It is an object of the present invention to provide an improved filter assembly which overcomes, or at least alleviates, the problems of known filter assemblies.
With that object in mind, the present invention broadly provides a filter assembly for filtering contaminants from liquid, including: a housing providing a filtering chamber and having an inlet port and an outlet port communicating with the chamber for flow of liquid therethrough.
Filter media is positioned in the filtering chamber for filtering contaminants from liquid flowing from the inlet port through the filter media to the outlet port.
A sump region is provided in the filtering chamber at the bottom thereof and spaced below the inlet port and toward which contaminants in the liquid entering the filtering chamber from the inlet port tend to gravitate for collection.
A separator member is located in the filtering chamber below the inlet port so as to substantially separate the filter media and sump region and so that gravitating contaminants gravitate from the inlet port to the separator member.
The separator member moves during use of the filter assembly, the movement facilitating separation of contaminants from the liquid entering through the inlet port and collection of contaminants in the sump region.
The separator member provides for communication of the contaminants into the sump region of the contaminants which have gravitated to the separator member and the separator member tending to trap therein the contaminants from the liquid received in the sump region.
In at least one embodiment, the separator member moves relative to the housing during use of the filter assembly.
This movement facilitates separation of the contaminants from the liquid and their collection in the sump region.
The separator member is preferably retained in the filtering chamber for vibratory movement caused by housing movement during use of the filter assembly.
In one arrangement, the separator member is preferably connected to the housing for its location within the filtering chamber
