ABSTRACT:
A fuel injection pump of the distribution type is provided with an electromagnetic valve for escaping the fuel in the pump chamber of the fuel injection pump. The fuel injection pump is also provided with a sensor for detecting the rotary angle of a pump shaft. This sensor is attached to a roller ring of a converter mechanism which also comprises a face cam, for example, and which also serves to convert the rotation of the pump shaft the reciprocate with that of a pump plunger. The sensor generates signals which represent the rotary angles of the pump shaft. The operation of the electromagnetic valve is controlled to escape the fuel in the pump chamber, depending upon the signals supplied from the sensor.
