Abstract
An oil burner having an atomizing nozzle receptive of a supply of oil through an oil tube therein and receptive of a supply of air under pressure through an air tube therein for atomizing the oil, includes an oil shut-off valve device which is responsive to the pressure of the air in the air tube for normally preventing the passage of oil from the oil tube to the nozzle until the air pressure rises above a given value and for shutting off the passage of oil from the oil tube to the nozzle when the air pressure falls below a given value.
