Aus
Die Aufgabe der Erfindung besteht darin, eine einfach zu bedienende und kostensparende Entlüftungsvorrichtung bereitzustellen.The The object of the invention is an easy-to-use and cost-saving venting device provide.
Die Aufgabe der Erfindung wird gelöst durch die Merkmale des unabhängigen Patentanspruchs.The The object of the invention is achieved by the characteristics of the independent Claim.
Weiterbildungen und vorteilhafte Ausführungen der Erfindung ist in den Figuren dargestellt; es zeigen:further developments and advantageous embodiments the invention is shown in the figures; show it:
In einer kostengünstigen Variante ragt der dem betätigten Zustand des 3/2-Wegeventils zugeordnete weitere Ausgang frei in den Motorraum, beipielsweise über einen Nippel, so dass nach Austreten einiger Tropfen Kraftstoff die Betätigung des 3/2-Wegeventils beendet wird. Die austretenden Kraftstofftropfen können beispielsweise über einen Becher aufgefangen werden.In a cost-effective Variant protrudes from the actuated State of the 3/2-way valve assigned further output freely in the engine compartment, for example, over a nipple, so that after leakage of a few drops of fuel the operation of the 3/2-way valve is ended. The exiting fuel droplets can for example via a Cup to be caught.
