ABSTRACT:
An electrically controlled fuel injection pump for internal combustion engines, in particular for direct fuel injection in engines having externally supplied ignition. A plurality of pump pistons driven by drive cams at a constant stroke and each leading into one cylinder bore, pump the fuel that has been brought to injection pressure in an associated pump work chamber to injection valves. A plurality of pump pistons are positioned side by side, radially of the camshaft. The work chambers of the pump pistons are connectable via a rotary slide valve to lines which lead to the injection valves and optionally to supply lines for supplying fuel to the work chambers of the pump pistons and the rotary slide can be driven in synchronism with the camshaft.
