Oil circuit
The fuel is pushed into the pump 1 to the nozzle 3 at the delivery pressure set by the pressure governor. The solenoid valve 2 stops the
fuel immission into the combustion chamber. The fuel flow rate that is not burnt goes back to the tank through the return circuit. The
spill-back nozzle is feeded at constant pressure, while the return line pressure is adjusted by means of the pressure governor controlled
by an actuator coupled to an adjusting cam. The fuel amount to be burnt is adjusted by means of the burner actuator according to the
adjustments set (see prevoius paragraph).
