Fuel injection pump for internal combustion engines

摘要

There is described a multicylinder fuel injection pump which is provided with a device that extends the length dimension thereof. The device includes a longitudinally shiftable piston disposed in a chamber that opens into the fuel injection pump. The shiftable piston includes perpendicularly disposed pin means arranged to cooperate with a fuel rack. In the rest position of the piston the regulating movements of the fuel rack caused by the governor are either unhindered because of the correspondingly long recess in the fuel rack, or limited to a predetermined travel path.
