Fuel SupplyHYDRAULIC CIRCUITSThe burners are fi tted with three valves (a safety valve and two oildelivery valves).A control device, on the basis of required output, regulates oildelivery valves opening, allowing light oil passage trough thevalves and the nozzle.Delivery valves opening supplies the two-stage hydraulic ramwhich regulates air delivery in relation to the fuel burnt.The pumping group is fitted whit a pump, an oil filter and aregulating valve, that adjust atomised pressure.Example of adjustable hydraulic ram of <strong>RL</strong> 34 - 44 MZ burners.<strong>RL</strong> 34 MZ<strong>RL</strong> 44 MZ - 50 - 64 MZVF2VF1U1U2VSVF2VF1U1U2VCVCPPADADMTMT<strong>RL</strong> 70 - 100 - 130<strong>RL</strong> 190VF2VF1VF2VF1VSU1U2VSU1U2VCPPADADMTMT<strong>RL</strong> 250 MZPVSVF1VF2MSMADU2U1PVSVF1VF2VCMTADU1U2Pump with fi lter and pressure regulator on the outputcircuitSafety valve on the output circuit1 st stage valve2 nd stage valve2 nd stage control deviceHydraulic ramAir damper1 st stage nozzle2 nd stage nozzle5
