Abstract
A valve includes an orifice disk element having at least two sheet metal layers lying in sandwich fashion against one another. The orifice disk element includes at least a base region with the opening geometry necessary for spray discharge of the medium, and a seat region with a valve seat surface, so that the valve seat and orifice disk function are combined in one metal laminate element. The valve is suitable in particular for use in fuel injection systems of mixture-compressing, spark-ignited internal combustion engines.
