Abstract
An air filter housing is provided for an intake air filter for a carburetor of an engine. A clean air receiving chamber is formed in the filter housing and is delimited by a filter element. Opening into the clean air receiving chamber is an intake opening that connects the air filter to the intake channel of the carburetor. A hood-like deflection bowl covers the intake opening in the clean air receiving chamber. The peripheral wall of the deflection bowl has a communicating window disposed transverse to the intake channel and serving for flow connection to the clean air receiving chamber. The communicating window opens into a compensation chamber that is separated from the clean air receiving chamber and communicates therewith via a channel.
