FLUID FILTER ASSEMBLY FOR VEHICLES

摘要

A snap-together, all-plastic filter assembly (20) for filtering fluids includes a generally cylindrical injection molded plastic outer shell (21) which has a closed base (36) and an open opposite end (35) and which defines a hollow interior which receives a filtering element (23) and an integral injection molded plastic end plate/center tube member (22). The outer shell is injection molded with a pair of concentric, generally cylindrical, inner annular walls (28a, 29a) which are integral with the closed base and extend part way toward the open end of the outer shell. The filtering element which has a hollow interior fits down within the outermost of the two concentric annular walls (29a) and the center tube of the end plate/center tube member extends through the center of the filtering element and snaps in place by means of snap-fit pockets (28b, 28c) disposed within the innermost of the two concentric annular walls.
