Oil bath air filter

The invention "refers to an oil bath air filter for internal combustion engines !! consisting of an oil container and a pilter head with a pilter head arranged both ways .

Invention ordered in the fact ₉ that ä <sr air inlet nozzle angularly adjoins © in zentriseli vertical tube ₉ aufruhtj the eiaer interposition Didi Tung on the filter insert which is in turn suspended in the oil reservoir "during ä®T hand the hood of the Filterkopffö &'- with the upper land of the oil container can be connected to "

For thorough cleaning of the oil bath filter, there is a filter layer in the filter housing

The air flow of unfiltered air through daa previously common elbow in the filter housing fluidly very unfavorable, resulting in a relatively high flow resistance results ₀ Infolg® d @ r crowded Einbauverhältliss® the filters in the vehicles leaving the! But not air management with a streamlined bend with * low Execute resistance «, Due to the high flow resistance of the elbow and the resulting increase in resistance of the filter», the fuel consumption of the combustion engine increases

In the oil bath air filter according to the invention the known disadvantages, such as poor cleaning possibility of the filter layer, increase the air resistance of the oil bath filter and manufacturing difficulties due to the elbow, avoided o The entire filter layer of the oil bath "= air filter is in the filter according to the invention

As a result, it is no longer necessary _{9 to} dismantle the filter when cleaning the filter from the suction line of the motor ₀

The pipe elbow in the usual construction is replaced by an elbow in which the knee leg lying in the axis consists of a sheet metal part, the circular area of which is at least $ 30 larger than the circular area of the leg that serves as the pipe air inlet nozzle in the filter housing «, As a result of the Cross-sectional expansion of the leg from the knee piece, the throttling effect of the knee piece is reduced, which results in a lower flow resistance for the air flow, compared to the usual right-angled pipe elbow In the filter insert sits ₉ retracted On the cylindrically retracted part of the leg, the filter insert is sealed with two lips that lie in the bore of the rubber ring. The main seal forms the sealing lip located in the direction of the filter axis, which hugs the conical transition from the cylindrically drawn-in part to the enlarged leg diameter, thus ensuring a practically absolute dust-air seal. The dust-tight seal on the other side of the knee takes place

through one embossed in the filter cover Centering shoulder on which the open leg side is inserted and with the centering shoulder e.g. "be glued with plastic glue can »so that the knee thigh is easily centric with the filter housing cover and dust-tight connected is,

To accommodate the leg of the knee piece, which serves as an air inlet nozzle and consists of a drill bit, the leg designed as a drawn part is perforated in the outer surface and the hole is provided with a collar onto which the drill bit is placed and glued to the drawn part. The hoop serving as an air inlet nozzle can be welded to the filter cover by means of a stitched seam or connected by soldering. An elbow manufactured in the manner described can not only be installed centrally seated in the filter cover without any effort, but it also requires a shorter manufacturing time compared to the tubular elbow commonly used up to now. "

The fact that the central inlet pipe is firmly inserted into a lip-like seal made of elastic material on the upper band of the filter and at the same time the edge of the hood of the filter head overlaps the band of the oil container, whereby an elastic seal is also provided, a very secure seal is guaranteed » which also against

Another? Ort @ il der erfintoigsgeiaäBen device consists in ₉ that the outlet nozzle with a large diameter is attached to the hood of the filter head and constantly see, "in ·
