してから供給するよつにしている。Conventionally, when supplying a relatively small amount of liquefied gas by vaporizing it, the liquefied gas was extracted from a liquefied gas cylinder placed at each customer, and this liquid was vaporized through the orifice of a pressure injection atomizer before being supplied. That's what I do. In addition, when generating a large amount of gas, a large number of cylinders are connected together, or liquid gas is forcibly heated and vaporized using a vaporizer before being supplied.

、安定した燃料供給ができなかった。In other words, air bubbles are generated in the piping from the cylinder due to the influence of the temperature of the piping and the drop in static pressure when flowing through the piping, and when these air bubbles pass through the orifice of the pressure injection atomizer, the flow rate fluctuates. There were problems when the liquid gas evaporated and icing formed at the orifice, making it impossible to provide stable fuel supply.

The liquefied gas container 1 and the pressure injection atomizer 2 are connected by a liquefied gas supply pipe 3, and the pressure injection atomizer 2 has a liquefied gas supply device that pressurizes the liquefied gas container 1 or the liquefied gas supply pipe 3. It consists of an outer cylinder 12 in which a nozzle part 10 is formed, a rotating body 13 and a valve body 15 that are fitted and fixed in the outer cylinder,
It is characterized in that the pressure between the nozzle section 10 and the rotating body 13 is set higher than the pressure at which the gas-liquid phase of the liquefied gas is balanced at atmospheric temperature.
