摘要： A filter filters fluid flowing along an axial flow direction and includes a plurality of concentric cylindrical pleated filter elements having a common axis. A plurality of annular radial gaps between filter elements provide additional flow axially through the filter, providing equalized flow and reducing restriction. In further embodiments, a central filter element is concentrically surrounded by a cylindrical pleated outer filter element and provides additional flow axially therethrough.

摘要： A filter (200) filters fluid flowing along an axial flow direction (14) and includes a plurality of panels (206, 208, 240, 242) of pleated filter elements (44), each filter element having a plurality of pleats defined by wall segments (50) extending along a transverse direction (210) between first and second sets of pleat tips at first and second sets of axially extending bend lines (46, 48), the transverse direction (210) being perpendicular to the axial direction (14). Each of the panels (206, 208, 240, 242) extends along a lateral direction (212) perpendicular to the axial direction (14) and perpendicular to the transverse direction (210). The wall segments (50) extend axially between upstream and downstream ends (52, 54), and define axial flow channels (55) therebetween which are alternately sealed at the upstream and downstream ends. Transverse gaps (214, 236, 238, 244, 246, 248) are provided between panels and the housing at upstream and downstream ends (52, 54), providing additional fluid flow axially therethrough and equalized contaminant passages.

摘要： A vortex air precleaner having snap-fit, self-sealing vortex tubes. Each vortex tube includes a flexible lip projecting laterally outward from the tube and spaced from an end of the tube. An annular shoulder is located between the lip and the tube end and spaced from the lip to provide a groove therebetween. The portion of the tube extending from the shoulder to the tube end is tapered inwardly and is formed with a plurality of longitudinal slits to provide the tube end portion with radial flexibility. When the tube end is inserted within an opening in the wall of the precleaner, the end portion will flex inwardly enabling the precleaner wall to be engaged with the groove, and the flexible lip engages the surface of the precleaner wall to provide a tight sealed joint.
摘要翻译：具有卡扣式自密封涡流管的涡流空气预清洗器。每个涡流管包括从管子横向向外突出并与管的一端间隔开的柔性唇缘。环形肩部位于唇缘和管端之间并且与唇缘间隔开以在其间提供凹槽。从肩部延伸到管端的管部分向内渐缩，并且形成有多个纵向狭缝，以使管端部具有径向的柔性。当管端插入在预滤器的壁的开口内时，端部将向内弯曲，使得预清洗器壁能够与凹槽接合，并且柔性唇缘接合预清洗器壁的表面以提供紧密的密封接头。
