ABSTRACT:
A venting valve for a fuel tank of a working tool driven by an internal combustion engine has a pressure compensation channel connecting the fuel tank interior to the surrounding atmosphere. A valve seat and a diaphragm are provided for closing off the pressure compensation channel when the diaphragm is seated on the valve seat. The diaphragm is lifted off the valve seat to open the pressure compensation channel when vacuum is present in the fuel tank interior. The valve seat is located at a first side of the diaphragm facing away from the fuel tank interior. The diaphragm has a central opening arranged centrally relative to the valve seat. A support plate is positioned at a second side of the diaphragm facing the fuel tank interior. It covers the deflecting area of the diaphragm and supports the diaphragm. The support plate has a sealing bead positioned in alignment with the valve seat. The spring forces the support plate and the diaphragm against the valve seat.
