Zusammenfassung:	A diaphragm carburetor for an internal combustion engine of a portable hand-held working tool has a housing with a control chamber. A suction channel extends through the housing and has a venturi section. An inlet valve is connected to the control chamber and supplies the control chamber with fuel. A main valve channel connects the control chamber to the venturi section of the suction channel. A check valve is positioned in the main valve channel adjacent to the control chamber and closes the main valve channel toward the control chamber. The main valve channel has a straight and elongate portion extending from the check valve into the venturi section and projecting into the suction channel.
