More Information
Summary:A valve, in particular, a fuel injector, has an improved sealing at its spray-side end. The fuel injector includes an excitable actuator for actuating a valve closing body, which together with a valve seat surface formed on a valve seat body forms a seal seat, and spray openings formed downstream of the valve seat surface, and a valve seat support, which accommodates the valve seat body, forms a portion of a valve housing and is fixedly connected to the valve seat body. A plastically deformable sealing element is introduced into an annular gap between the valve seat support and the valve seat body to avoid corrosion and damage of a weld seam.
