Patent attributes
A venting valve for a fuel vessel of a portable handheld work apparatus has a valve housing which includes a base body and a valve cover. A valve plate is mounted between the base body and the valve cover. The valve plate controls a pressure compensating channel connecting the vessel interior space to the outside of the vessel. A cover cap extends over the valve cover and is fixed with an attachment shoulder on the base body. To reliably prevent a separation of the cover cap from the base body, a collar is provided on the liquid vessel wherein the attachment shoulder of the cover cap engages. The collar overlaps the free end of the attachment shoulder over a pregiven axial length (L). The inner diameter (I) of the collar is configured only slightly greater than the outer diameter (A) of the free end of the attachment shoulder.
