ABSTRACT:
A gas candle, comprising a cylindrical casing divided by a division plate into a first chamber at the bottom for containing illuminating gas and a second chamber at the top for holding a gas flow rate control device. The division plate has a gas outlet hole at the center through which illuminating gas is permitted to discharge into the second chamber. The gas flow rate control device has an outer thread screwed up with the inner thread on the second chamber, a nozzle tip defining a gas passage way longitudinally piercing through the body of the gas flow rate control device, an annular groove on the periphery thereof at a lower end with an O-ring mounted thereon to seal the gap between the gas flow rate control device and the cylindrical casing. A sealing cover is mounted on the division plate at the top to seal the gas outlet hole. A pressure cushion is mounted on the seal cover at the top, having a pin at the top for inserting in the gas passage way of the gas flow rate regulating device from the bottom. By rotating the gas flow rate regulating device in the cylindrical casing in clockwise or counter-clockwise direction, gas flow rate through the gas outlet hole and the nozzle tip is controlled.
