Abstract

734,302. Liquid-fuel burners. PARSONS & MARINE ENGINEERING TURBINE RESEARCH & DEVELOPMENT ASSOCIATION. Aug. 31, 1953 [Dec. 22, 1952], No. 32466/52. Class 75 (1). In an oil fuel sprayer of the spilltype in which when no oil is required to be sprayed a change-over valve is operated to supply oil to the spill duct to close a spray nozzle valve and to pass through the sprayer to the supply duct, the nozzle valve k forms part of a plunger embodying a pistonlike enlargement h<SP>11</SP> which co-operates with the bore of a tube f to provide an axial flow passage p<SP>1</SP>, Fig. 1, when the valve is closed and which co-operates with an enlarged part of the bore to provide a passage P<SP>11</SP>, Fig. 2, of considerably greater cross-section when the valve is open. The nozzle valve k is held closed by a weak spring m, when oil is supplied through passages j, j<SP>1</SP> (the spill ducts during operation of the burner) and through the constricted passage p<SP>1</SP> past a further plunger enlargement h<SP>1</SP>, and thence into the swirl chamber el to pass therefrom through tangential passages f<SP>11</SP>, annular passage e, and an opening d. In operation, fuel is fed through the opening d, and passages e and f<SP>11</SP> to the swirl chamber el to unseat the valve k, so that fuel is discharged through the opening b<SP>1</SP>, the excess fuel passing to the spill duct through axial grooves i<SP>1</SP> in the plunger enlargement h<SP>1</SP> which is received in a portion of the bore of the tube f of reduced diameter when the valve is open, and through passages p<SP>11</SP>, j<SP>1</SP>, and the opening j. A stop o carried by an adjustable plug n limits the opening movement of the plunger h. The openings d, j may be connected to a changeover valve to which fuel is supplied by a pump and from which fuel may be withdrawn to the suction side of the pump through a throttle valve for controlling the burner discharge. The supply and spill pipes of a plurality of changeover valves each associated with an individual sprayer, may be connected in parallel.
