摘要

Fuel injection valves for internal combustion engines wherein the valve seat body is produced by a series of complex operating methods are already known. With the novel valve, a valve seat body which is of simple design and can be produced economically is used. The valve seat body (16) is made by stamping and deep-drawing sheet metal, and is pot-shaped with a seat body base (19) and a seat body annular edge (20). Formed in the seat body base (19) is a valve seat (24). A perforated injection plate (34) is welded to the valve seat body (16). The fuel injection valve is particularly suitable for fuel injection systems of mixture-compressing, spark-ignition engines.
