Abstract
A diaphragm carburettor is connected via a suction port with the clean air side of an air filter. A regulating chamber with a fuel chamber is connected with the suction port, in which the fuel chamber is acted upon with underpressure from the suction port and is separated from a compensation chamber by a regulating diaphragm formed to control the fuel supply to the fuel chamber. The compensation chamber is connected via a compensation path with the clean air side of the air filter and/or with the suction port so that pressure vibrations are reduced in the compensation chamber. A control and/or regulating element associated with the compensation path alters the length and/or the diameter of the compensation path.
