Abstract

The invention relates to an air cleaner comprising a generally bell-shaped air cleaner housing and a generally frustoconical filter positioned concentrically within the housing. The housing has an air inlet at its small end and an air outlet at its large end for the flow of air generally axially into and out of the housing. The filter has a filter element coaxially juxtaposed the interior surface of the housing. The filter element is generally annular and has an upstream portion and a downstream portion. The downstream portion of a member supportably engages the upstream portion of the filter element. The upstream portion of the filter element has a diameter larger than the diameter of the member downstream portion. The member blocks the flow of air into the interior of the filter element and directs air axially along the exterior of the filter element. A downstream annular support piece engages the downstream end of the filter element. The support piece has an aperture communicating with the outlet and with the interior of the filter element. The support piece sealably engages the interior surface of the housing. Air flowing in an axial direction through the inlet passes over the member, axially along the filter element a distance before passing through into the interior of the element and axially out the outlet.
