Abstract
A fuel injector is described having a movable valve part, which for opening and closing of the valve cooperates with a stationary valve seat which is formed on a valve seat element. A swirl disk is arranged downstream from the valve seat and has a multilayer configuration. The fuel flowing through is imparted to a swirl component between at least one inlet area and at least one outlet area. In a first swirl-generating plane a swirl component is imparted to a first portion of the flow, while a second portion of the flow without swirl and independent of the first swirling portion of the flow is routed inside the swirl disk, and in a second swirl-generating plane a swirl component is imparted only to the second portion of the flow. The fuel injector may be suitable for direct injection of fuel into a combustion chamber of an internal combustion engine having compression of a fuel/air mixture with spark ignition.
