In general, a heat exchanger is supplied with a liquid at a critical pressure or higher pressure in order to suppress boiling, but the gas obtained in the vaporizer behind the heat exchanger has a relatively low pressure. Yes, a complicated system with a loss of efficiency is required to supply the liquid to the heat exchanger by converting the energy state of the gas obtained into kinetic energy or electrical energy and boosting it with a mechanical pump. In addition, there is no solution, and it has been difficult to reduce the weight of the propellant supply device and simplify the system in moving bodies, particularly flying bodies. Using a relatively low-pressure gas itself obtained by vaporizing a liquid, it is not necessary to convert the energy state of the gas into kinetic energy or electric energy. The present invention provides a device of the present invention that pressurizes and supplies a high pressure, and provides a system and method using the device for supplying a propellant in a moving object, particularly a flying object.
