AIR CLEANER OF INTERVAL COMBUSTION ENGINE Russian patent published in 2007 - IPC F02M35/24 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed air cleaner of internal combustion engine contains filtering element secured inside sectional envelope, one half of which has air supply branch pipe, and second one, air supply and air discharge branch pipes. Halves of envelope are connected to each other by flexible catches uniformly spaced in cutouts of connecting flange of one half fitted in retainers of other half through cutouts in its connecting flange to permit arrangement of halves at different angles relative to one another. Thin-walled skirt made in one half of envelope projects beyond the limits of connecting flange whose outer surface is in contact with inner surface of other halt. Catches on one and retainers on other half are spaced relative to each other through 30°C. Thickened portions are found on free end of catches, and cavities are made in retainers in place of their contact with second half. Undercut is made in center of bottom of first half, side surface of which is in contact with inner surface of seal of filtering element. Support branch pipe is made inside second half concentrically to air discharge branch pipe, outer surface of which is in contact with inner surface of second seal of filtering element. Halves of sectional envelope are made of polymeric material.

EFFECT: simplified design, reduced cost of production.
