Liquid filter with a centrifugal separator includes an annular filter element having an array of canted fins at one end for creating a swirling liquid flow in a cylindrical housing.

摘要

A filter element (12) for filtering a liquid is mounted in a cylindrical housing (14) into which liquid enters at one end adjacent to the filter element and comprises: (1) an annular filter media the ends (of which are located adjacent the ends (20, 22) of the housing; and (2) an array (40) of radially projecting fins (42) adjacent the liquid entry end of the housing which are oriented to import a rotary motion to the liquid so that particulates (43) migrate under centrifugal force away from the filter media.
