Abstract
In a fuel injector, a spherical valve-closure member interacts with an edge seat. The edge seat is formed by surfaces that follow one another directly at different angles in the area of the valve seat. The angles of the surfaces are such that the sealing edge of the edge seat points toward the valve-closure member. The fuel injector is especially suited for applications in fuel injection systems of mixture-compressing internal combustion engines having externally supplied ignition.
