Air intake filters for internal combustion engines

The invention relates to an intake air filter for internal combustion engines with a pipeline connection arranged on the clean air duct for venting the crankcase of the internal combustion engine. In known intake air filters of this type, the pipe connection for venting the crankcase is provided in the form of a pipe socket which ends at any point on the filter housing on the clean air side. The negative pressure that can be achieved in this way, which depends on the amount of air drawn through and the flow resistance of the part of the> mer ₈ arranged in the vent line, is not always sufficient to vent the crankcase effectively

It has also been suggested, the Mündestell® arrange for the pipe connection in the wall of the suction pipe and train it as a suction nozzle In this way the amount of gas sucked out of the crankcase was increased considerably, but it was found
