ABSTRACT:
A boost compensator for controlling the position of a control rack of a fuel injection pump to supply fuel to an internal combustion engine with a supercharger in response to boost pressure to be applied to the engine. The control rack is moved in a direction increasing an amount of fuel to be supplied to the engine, by angular movement of a main lever in one direction during forward movement of a push rod in response to an increase in the boost pressure from a first to a second set value. As the boost pressure reaches a third set value higher than the second set value, the push rod is brought into engagement with an auxiliary lever biased by a return spring. As the boost pressure exceeds the third set value, further forward movement of the push rod causes the auxiliary lever to angularly move against the return spring to bring an abutment member carried on the auxiliary lever into engagement with the main lever, causing the main lever to angularly move in the opposite direction to move the control rack in a direction decreasing the amount of fuel to be supplied to the engine.
