摘要：A filter (10, 10a) includes a housing (12, 12a) extending along an axis (14) andhaving an inlet (16, 16a) at one axial end (18, 18a) of the housing and having an outlet (20,20a) at a distally opposite axial end (22, 22a) of the housing. One or more pleated filterelements (44, 44a, 44b, 44c, 44d) in the housing are pleated along a plurality of bendlines (46, 48) extending axially. The filter element has a plurality of wall segments (50)extending in serpentine manner between the bend lines. The wall segments extendaxially bet veen upstream ends (52) and downstream ends () and define axial flowchannels (58, 62) therebetween. The upstream ends of the wall segments are alternatelysealed (56) to each other to define a first set of flow channels (58) having open upstreamends (60), and a second set of flow channels (62) interdigitated with the first set of flowchannels and having closed upstream ends (). The downstream ends of the wallsegments are alternately sealed to each other (66) such that the first set of flowchannels have closed downstream ends (68), and the second set of flow channels haveopen downstream ends (70). Fluid to be filtered flows substantially directly axiallythrough the filter element (44) or elements (44a, 44b, 44c, 44d), through the open

upstream ends of the first set of flow channels then through the wall segments thenthrough the open downstream ends of the second set of flow channels. A gasket (82, 82a,82b, 82c) seals the filter element to the housing.
