Disposable air filter assembly and method of making same

Patent ·
OSTI ID:7241891
An air filter assembly is described for use with an internal combustion engine comprising a housing having opposed end walls and an outer wall coacting to form an interior air flow passageway, an inlet for the passageway formed on the exterior of the housing and an outlet for the passageway formed in one of the end walls for communicating with an engine manifold. A filter member is disposed within the passageway and enclosed within the housing, the end and outer walls are initially of unitary construction, one end wall having a predetermined section thereof subsequently severed from the housing so as to expose at least a portion of the interior passageway whereby the filter member is inserted into the passageway. When severing the one end wall section from the housing, an annular segment of the housing is removed whereby a collar is formed on the exterior of the remainder of the housing and a peripheral flange is formed on the severed end wall section. The flange is sized to snugly fit within the collar when the severed end wall section is re-attached to the remainder of housing subsequent to the filter member being disposed within the passageway.
