Abstract
A fuel injection valve for high-pressure injection of fuel from a central high-pressure line into combustion chambers of an internal combustion engine, which includes a switching valve with a valve seat and a valve ball; the valve ball in the opened state is lifted from the valve seat by means of a high-pressure jet which is supplied from a throttle bore by a pressure chamber operatively connected to a central high-pressure line. The transition from the throttle bore to the valve seat is embodied as a diffuser.
