ABSTRACT:
The invention relates to a membrane carburetor having an air filter connected upstream of the intake channel. The combustion air passes through the air filter and into the intake channel of the carburetor and coacts with the fuel drawn into the intake channel to form a fuel/air-mixture which enters the combustion chamber of the engine communicating with the intake channel. The compensation chamber of the carburetor is connected exclusively to the clean-air side of the air filter in order to avoid an overenrichment of the mixture when the filter material of the air filter becomes contaminated. The membrane carburetor can be used on two-stroke engines for portable handheld tools such as motor chain saws, cutoff machines, brushcutters or the like.
