ABSTRACT:
A boost compensator has a valve operative in response to a boost pressure. When the boost pressure is equal to or lower than a setting pressure, the valve intercepts communication between first and second chambers of the boost compensator which are partitioned by a diaphragm. When the boost pressure exceeds the setting pressure, the valve brings the first and second chambers into communication with each other. By the communication, pressure within the second chamber is raised so that the diaphragm and a push rod operatively connected to the diaphragm are moved toward the first chamber. As a result, a control member of a fuel injection pump is caused to be moved in a fuel decreasing direction.
