Fuel injection pump for internal combustion engines

A fuel injection pump for internal combustion engines having a pump interior, a pump housing therefor provided with a pump work chamber, a quantity adjusting device disposed in said pump interior for controlling the fuel injection quantity pump at high pressure by a pump piston, a control mechanism chamber separate from said pump interior and arranged to communicate therewith via a fuel flow throttle restriction, said control mechanism chamber also being arranged to communicate via an overflow valve with a fuel return line leading to a fuel tank, an electric control mechanism disposed in said control mechanism chamber adapted to actuate the quantity adjusting device, said electrical control mechanism having connections electrically secured on a circuit board in said control mechanism chamber, said control mechanism chamber (36;

• 436) further including an electric temperature sensor (46;
• 146;
• 246;
• 346;
• 446;
• 546) having a temperature-sensitive sensor element (47;
• 147;
• 247;
• 347;
• 447;
• 547) which at least with its sensor element (47-547) dips into a fuel flow means which permanently diverts fuel from the pump interior (10) into said control mechanism chamber, and further that said temperature sensor (46-546) has electric connecting leads which extend to said circuit board (35) and are secured electrically thereto.
