Abstract

A filter assembly includes a filter housing, a filter housing lid, a filter cartridge, an endplate, and a seal member. The filter housing defines a first cavity and comprises a return passage in fluid communication with the first cavity. The filter housing lid is selectively coupled to the filter housing and defines a second cavity coextensive with the first cavity. The filter cartridge is positioned within the first cavity. The endplate is coupled to a first end of the filter cartridge. The endplate is configured to interface with the filter housing. The seal member is coupled to the endplate and is configured to be received in the return passage. The endplate is configured to partially separate the filter housing from the filter cartridge.

Claims25

Dependent claims

A filter assembly comprising:

a filter housing defining a first cavity and comprising:
a first surface, and
a return passage in fluid communication with the first cavity, the return passage extending through the first surface;
a filter cartridge positioned within the first cavity, the filter cartridge centered on a center axis;
an endplate coupled to a first end of the filter cartridge, the endplate configured to partially separate the filter housing from the filter cartridge, the endplate comprising an endplate aperture extending around the center axis;
and
a seal member extending around the center axis, the seal member comprising:
a seal member projection configured to be received within the endplate aperture so as to couple the seal member to the endplate;
and
a seal member flange integrally formed with the seal member projection and configured to be received in the return passage when the endplate is in confronting relation with the first surface, protrude from the endplate when the seal member projection is received within the endplate aperture, and deflect relative to the seal member projection when the seal member projection is received within the endplate aperture.

7 more elements

A filter assembly for a filter cartridge assembly, the filter assembly comprising a filter housing configured to receive the filter cartridge assembly and including:

an inlet passage configured to receive fluid from a fluid source;
a filter housing inlet configured to receive fluid from the inlet passage and provide fluid to the filter cartridge assembly when the filter cartridge assembly is received within the filter housing;
a filter housing outlet configured to receive fluid from the filter cartridge assembly when the filter cartridge assembly is received within the filter housing;
and
a return passage configured to removably receive a seal member coupled to the filter cartridge assembly when the filter cartridge assembly is received within the filter housing, the return passage configured to receive fluid when the filter cartridge assembly is removed from the filter housing, provide fluid to the inlet passage, and be isolated from fluid within the filter cartridge assembly when the seal member is received within the return passage, the return passage fluidly coupled to the filter housing inlet via the inlet passage.
