ABSTRACT:
A fuel injection pump for internal combustion engines, in particular an in-line injection pump for Diesel engines, is proposed having an injection quantity governor and an electrically driven feed pump, in which in order to assure an emergency shutoff in the event of a malfunction of the injection quantity governor, a check valve, the forward flow direction of which is toward a suction chamber filled with fuel by the feed pump, is disposed between the pressure-side outlet of the feed pump and the suction chamber. An emergency shutoff device responding to a malfunction switches off the feed pump drive, so that because of the lack of feed pressure the check valve closes and blocks off the suction chamber. The engine comes to a stop, as soon as a partial vacuum is established in the suction chamber, which occurs as soon as several revolutions later.
