METHOD OF AND DEVICE FOR MANUFACTURE OF AIR CLEANER Russian patent published in 2007 - IPC F02M35/24 

FIELD: mechanical engineering; engines.

SUBSTANCE: relates to methods of manufacture of air cleaners with filtering elements mainly of panel-type for cleaning air getting into internal combustion engines of road vehicles, and into devices in which proposed methods can be implemented./ proposed method comes to preliminary manufacture of filtering element including the following operations: bending of tape of filtering material at preset pitch, corrugating of tape in corrugating device and folding material along bending lines, placing filtering element, thus made, between two housing halves, lower and upper ones, made of plastic by injection molding method, hermetically connecting housing halves by fasteners and mounting of mass meter in zone of cleaned air on upper housing half. Novelty is that air is delivered under pressure inside air cleaner to zone of non-cleaned air through air inlet branch pipe of lower housing half before mounting air mass meter on upper housing half, and blowing out of filtering element and inner surface of upper housing half is carried out to provide complete cleaning of their surfaces from side of zone of cleaned air of upper housing half. Blowing air can be delivered in pulsating manner. Then air gets out through air outlet branch pipe of upper housing half into ambient atmosphere, after which air delivery into space of air cleaner is stopped and air mass meter is mounted which is hermetically closed by dummy stopper. Invention contains description of device by means of which proposed method can be industrially implemented.

EFFECT: provision of device for reliable cleaning of air.
