Abstract
An injection quantity increasing mechanism for a governor in a fuel injection pump which is actuated at engine starting includes a guide lever and a torque cam both rotatable in accordance with the rpm of an engine, a floating lever swingably connected to the guide lever, a control lever for controlling the engine rpm and a control rack for controlling the fuel injection quantity both associated with the floating lever, and a stop device lever adapted to be displaced in a direction which decreases the fuel injection quantity and is associated with the control rack. This mechanism is characterized in that the control lever and the floating lever are swingably connected to each other by first and second supporting levers which are swingable relative to each other and in that the swinging motion of the first and second supporting levers offsets displacements from the control rack and from the guide lever exerted on the floating lever when the stop device lever performs its stop function to maintain the rotational position of the torque cam.
