Abstract
Abstract THE INVENTION RELATES TO PRESSURE JET BURNER CONTROL SYSTEMS INCLUDING A MOTOR DRIVEN FUEL PUMP WHICH STOPS AND STARTS ACCORDING TOE TH EFUEL REQUIREMENTS OF THE BURNER AND IN WHICH CUT-OFF AND START-UP OF THE FUEL SPRAY IN THE BURNER IS ADRUPT AND THE PRESSURE OF FUEL IS MAINTAINED ABOVE A PREDETERMINED MINIMUM PRESSURE OF THE VOLUME. FUEL SUPPLY TO THE BURNER IS CONTROLLED BY A QUICK CUT-OFF VALVE ARRANGED TO START AND CUT OFF FUEL AT PREDETERMINED FUEL PRESSURE AND ALSO INCLUDES A BY-PASS LINE CONNECTED IN THE FUEL LINE BETWEEN THE CUT-OFF VALVE AND THE PUMP, AID BYPASS LINE BEING CONTROLLED BY A SOLENOID VALVE WHICH SIMULTANEOUSLY RELIEVES FUEL TRAPPED IN SAID FUEL LINE UNDER PRESSURE WHEN THE FUEL PUMP IS DEENERIGISED.
