US Patent 12129973 Liquefied fluid supply system and liquefied fluid-spraying apparatus

A liquefied fluid supply system is a liquefied fluid supply system of supplying a nozzle with a liquefied fluid that vaporizes after spraying and includes: a supercooler that cools the liquefied fluid to a temperature lower than a saturation temperature thereof and makes the liquefied fluid into a supercooled liquid; and a booster that boosts in pressure the liquefied fluid made into the supercooled liquid by the supercooler and supplies the liquefied fluid to the nozzle.
