Patent ID: 8241494

Claim:
A liquid filter assembly comprising: a first liquid filter element adapted to filter particles larger than a first size; a second different liquid filter element adapted to filter particles larger than a second size, the second size being smaller than the first size, where the second filter element comprises a polymer porous member, where the second filter element is a one-piece member with a substantially solid, rigid disk shape, and where the one-piece member has a general disk shape with a height substantially smaller than a width of the general disk shape; a holder having a bottom side located at a top side of the first filter element, wherein the holder has a portion located along a side height of a lateral outer side of the second liquid filter element such that the second liquid filter element is retained in a seat of the holder; a housing having the first and second liquid filter elements therein, the liquid filter assembly forming a first liquid flow path having the first liquid filter element therein and a second liquid flow path having the second liquid filter element therein, wherein the first and second flow paths are at least partially separate; and a spring located directly between the one-piece member and the housing, wherein the spring directly biases the one-piece member directly against the holder.
