Claims

[Scope of utility model registration request]

Flyweight 1 that tilts according to the engine operating condition
2, the displacement of the thruster 4 of the centrifugal weight device 2 is controlled between the thruster 4 of the centrifugal weight device 2 and the metering rack 1 of the fuel injection pump. A holder disposed opposite an appropriate position of an injection amount control mechanism section 49 connected by an appropriate lever mechanism 3 so as to be able to control the fuel injection amount as appropriate by transmitting the information to the metering rack 1 of the fuel injection pump. A stopper member 22 which is biased with an appropriate spring force by a spring 23 and can be moved forward and backward by an appropriate amount is fitted into the interior of the metering rack 1. This is an injection amount limiting device for a fuel injection pump configured to be able to limit the maximum injection amount of the fuel injection pump by appropriately regulating the displacement of the fuel injection pump. At temperatures above a predetermined temperature, the fuel injection pump deforms in a direction that increases the maximum limited injection amount of the fuel injection pump limited by the stopper member 22, and below a predetermined temperature, it deforms in a direction that decreases the maximum limited injection amount of the fuel injection pump. - An injection amount limiting device for a fuel injection pump, characterized in that a shim member 30 made of a shape memory alloy is interposed.
