A plurality of notches are arranged in the nozzle funnel and extend essentially radial to the nozzle bore. Each notch has an inlet wall, a baffle wall, a radially outer notch inlet, and a radially inner notch outlet. Each notch further includes an essentially flat notch bottom arranged between the inlet wall and the baffle wall.
