ABSTRACT:
A fuel pressure regulator controls the pressure differential across a nozzle which is subject to variations in exhaust gas backpressure having a solenoid actuated valve member which is actuable in response to signals from a controller to establish a predetermined fuel pressure across the nozzle consistent with a control strategy. A pressure dependent valve actuator is operable on the valve member, independently of the solenoid, to adjust the valve opening and, as such, the fuel pressure at the nozzle to adjust the fuel pressure in response to exhaust gas.
