ABSTRACT:
A regulator shaft, rotary centrifugal weights, and a governor member which is slidable on the regulator shaft, are arranged in a pressurized, fuel-filled inner chamber of a fuel injection apparatus. The centrifugal weights engage regulator springs via the governor member and a control sleeve. The governor member is closed adjacent the free end of the regulator shaft except for a throttle opening for communication with the inner chamber. The governor member is provided with a work chamber, one extremity of which is limited by the regulator shaft. A conduit leading to a fuel tank communicates with the work chamber. A magnetic valve connected to an electronic control device for control of the fuel flow is provided in the conduit. Opening the magnetic valve causes a pressure drop in the work chamber which in turn causes the governor member to press against the centrifugal weights, thus enhancing the fuel injection quantity so as to reduce deviations from those desired and pre-set.
