摘要:
A device for a combined blowout of fuel and air for fuel injection systems in internal combustion engines having a housing with fuel and air connections and a hollow, elongated housing neck having a blowout opening on an end that communicates with the fuel and air connection. Disposed on an end of the housing neck is an electromagnetically actuated valve element, which is pressed onto a valve seat by a valve closing spring. To make the device more efficient for fuel preparation, the valve seat is disposed on a coaxial inner tube that penetrates the housing neck and which extends into the blowout opening. The outer diameter of the inner tube is smaller than the inside diameter of the housing neck. The interior of the inner tube communicates with the fuel connection and the annular chamber enclosed by the inner tube and the housing neck communicates with the air connection.
