Claims

[Scope of utility model registration request]

The inside of the main body is partitioned by a diaphragm into a pressurizing chamber into which supercharging pressure is introduced and an atmospheric chamber, and when the supercharging pressure introduced into the pressurizing chamber reaches a set pressure, the diaphragm is activated. In a boost compensator that moves a control rack of an injection pump in a fuel increasing direction in conjunction with the operation of a diaphragm, a first opening/closing operation for opening/closing a supercharging pressure introduction passage that introduces supercharging pressure into a pressurizing chamber of the main body. In addition to providing a valve, a high-pressure air introduction passage connected to the pressurizing chamber of the main body and equipped with a second on-off valve is provided, and when the engine is started at a low temperature, the first on-off valve is closed and the second on-off valve is closed. A tossle-foust compensator characterized in that it is opened to introduce high-pressure air into the pressurizing chamber and move the control rack of the injection pump in the direction of fuel increase.
