The governor of the distributing fuel injection pump for diesel engine

摘要

The sleeve is linearly reciprocated using the centrifugal force of the driven gear rotated by the engine on the governor shaft and the displacement of the control sleeve through the lever assembly operated by the sleeve adjusts the effective stroke of the distribution plunger, The present invention relates to a governor of a distributing fuel injection pump for a diesel engine which controls the amount of fuel injected by a fuel injection valve, and the displacement of the sleeve is nonlinearly formed by the shape of the profile, so that an optimum fuel injection amount required by the engine is realized. To this end, the present invention is characterized in that the sleeve 13 is slidably inserted into the end of the governor shaft 3; A profile plate (37) in contact with the sleeve is slidably engaged with the governor shaft; The weight element 39 that is in contact with the profile surface 37a of the profile plate is mounted on the inside of the holder 43 connected to the driven gear 7 rotatably provided on the governor shaft via the spring 41 , And is constructed so as to spread radially over the spring force by the centrifugal force of the driven gear (7). According to this configuration, the profile plate can be precisely controlled in a nonlinear manner with respect to the centrifugal force of the weight element in accordance with the shape of the profile surface, so that the optimum fuel injection amount required by the engine can be realized.
