Claims

[Scope of utility model registration request]

A control sleeve controlled by a governor lever mechanism consisting of a collector lever supported by a fixed support shaft and pressed against a full load adjusting screw by a support spring, and a tension lever and a start lever supported by a support shaft on the collector lever. In a distributed fuel injection bonding device that increases or decreases the fuel injection amount by changing the effective stroke of the plunger, a temperature-sensitive actuating member made of a shape memory alloy is disposed in the full load adjusting screw part and the support spring part, and when the fuel is low temperature, The temperature-sensitive operating member made of the shape memory alloy is set so that the collector lever can be rotated in the direction of increasing the injection amount, returned to the direction of decreasing the injection amount at normal temperature, and rotated in the direction of increasing the injection amount at high temperature. Features a temperature-compensated distribution fuel injection pump.
