Abstract: The present disclosure relates to an air cleaner for moving particles from an air stream. The air cleaner includes a housing defining a separation chamber at which at least some of the particles are removed from the air stream. The air cleaner includes an inlet passage for allowing the air stream to the separation chamber, an outlet passage for allowing the air stream to exit the separation chamber, and a plurality of vanes for causing the air stream to swirl as the air stream flows through the inlet passage and enters the separation chamber. The housing includes a side wall structure defining at least one discharge opening through which particles are discharged as the air stream swirls within the separation chamber.

Abstract: Air conduit construction is provided. The construction generally comprises a conduit section having an open end; and, a support member positioned inside of the conduit section open end. In preferred arrangements, the conduit construction has two open ends, with a reinforcing member in each of the open ends. In preferred arrangements, the reinforcing member includes a friction fit construction on an outer surface thereof. In typical and preferred embodiments, the friction fit construction includes a bead on the reinforcing member. A method of preparing air conduit constructions is also provided.

Abstract: An air flow conduit system is presented for air flow communicatoin between an air filter mechanism and an engine intake manifold. The conduit system comprises substantially rigid straight conduit members joined in fluid communication by connector systems having elbow-shaped conduit members. A narrow end of a conduit member is received within a broad end of a next adjacent conduit member. Sealing engagement occurs by means of an elastomeric seal member having ribs thereon positioned radially between the inner and outer conduits. A preferred rib arrangement is provided, to insure a flexible, multipoint, seal system.

Abstract: A quarter turn fastener (10) fastens a first component (12) to a second component (14). The fastener (10) has a cap (20) covering and rotating about a cylindrical mounting member (24) with a spring (34) therebetween. The mounting member (24) attaches to the first component (12) by barbs (28). Rotation is limited by a slot and tab arrangement having a tab (42) extending inward from the cap (20) into a slot (44) in the mounting member (24). The slot (44) extends one fourth of the way around the circumference of the mounting member (24) for limiting rotation and includes ridges (46, 48) preventing free rotation of the tab (42) at the ends of the slot (44). A shaft (36) attached to the cap (20) and extends through the mounting member (24), first component (12) and second component (14). A curved retainer member (38) engages slot (18) and has sloping engaging surfaces (52, 54, 56) for guiding the retainer member (38) into and out of the slot (18) when the fastener (10) is twisted.

Abstract: An air flow conduit system is presented for air flow communication between an air filter mechanism and an engine intake manifold. The conduit system comprises first, second and third substantially rigid conduit members. Engagement between conduit members is provided by a rib system on a narrow end of a conduit member being received within a broad end of a next adjacent conduit member. Sealing engagement occurs by an elastomeric seal member positioned between the ribs and an end of a conduit member within which the ribs are received. A preferred rib arrangement is provided, to insure a flexible, multi-point, seal system.
