PURPOSE: To provide an improved type fuel supplying device to improve efficiency and be safely worked. CONSTITUTION: A fuel supplying device to supply fuel to a compression ignition engine consists of a rotary distribution member 11 having a feed passage 13 engaged, in order, with an outlet port 14 connected to the injection nozzle of an engine. Fuel is fed from an accumulator 20 to a feed passage through control of a valve 18. The accumulator is filled with fuel by a high pressure pump 8 being a cam-operated pump and the fuel is fed to a high pressure pump by a low pressure pump 31. An electrically controlled pressure control valve 34 controls the output pressure of the low pressure pump so that an amount of fuel fed to a high pressure pump is changeable to control a fuel pressure in the accumulator. The pressure is sensed by a transducer pressure sensor 35 to feed a signal to an electronic control device 22 to control a flow of a current in the valve. |
