AIR-CLEANER Russian patent published in 2008 - IPC F02M35/08 

FIELD: mechanical engineering; transport engineering.

SUBSTANCE: invention relates is to large-size air cleaners of vehicle. Proposed air cleaner contains housing, separating holes arranged in housing in each of which flow swirler is fitted from side of input. Dust-collecting pan with dust suction branch pipe and cleaned air intake cones is connected to housing. Each intake cone is arranged from side of vertex with clearance inside output section of separating hole to form ring channel. Port with intersection of wall of separating hole is made near each separating hole from side of base. Housing is assembly of monoblocks rigidly connected to each other. Dust collecting pan consists of monoblocks. Monoblocks are hermetically connected by welding. Flow swirler is blade-type, with central bushing, and is secured on intake cone. Intake cone is provided with slots to pass cleaned air. Dust-collecting pan is connected to housing by studs and nuts. Intake cones are fastened to dust-collecting pan by welding (metal ones) or gluing (plastic ones). Monoblock can be assembled and rigidly interconnected on board by means of screw which are not shown in Drawing, or by any other method.

EFFECT: improved reliability and economy of air clearance.
