Claims

[Scope of utility model registration request]

A fuel injection pump that can adjust the amount of injection into the engine by operating an injection amount adjustment rack includes a temperature-responsive member that expands and contracts in accordance with the temperature of the engine, and a temperature-responsive member that expands and contracts according to the temperature of the engine, and the temperature-responsive member that responds to the displacement of the expansion and contraction end of the temperature-responsive member. a limiter member for regulating the maximum injection amount position of the injection amount adjustment rack, the temperature responsive member is arranged so that its expansion and contraction direction is substantially perpendicular to the moving direction of the injection amount adjustment rack; A limiter member is fixed to the telescopic end of the temperature responsive member and is formed with a cam surface along the direction of displacement thereof,
An injection amount control device for a fuel injection pump, characterized in that the injection amount adjustment rack is provided with a protrusion that comes into contact with the cam surface when the fuel injection pump injects maximum fuel to the engine.
