[0021] Examples:
[0022] See figure 1 As shown, the liquid fuel micro propulsion system of the present invention mainly includes: a pressurized gas generator 1, a micro thruster 12, a fuel tank 4 that provides liquid fuel for the micro thruster 12, and the pressurized gas generator 1 is used for fuel The storage tank 4 is inflated and pressurized; the fuel storage tank 4 is separated by a diaphragm 5 into a liquid storage portion 42 for storing liquid fuel, and a gas storage portion 41 that communicates with the pressurized gas generator 1 through a gas pipeline 13 to reduce The amount of medicine in the pressurized gas generator is pre-filled with carbon dioxide gas in the gas storage part 41 of the fuel storage tank 4. The function of the diaphragm 5 is to separate the liquid fuel from the pressurized gas, which can make the liquid in the weightless state of space. Without entrained air bubbles, a pressure sensor 2 and a gas addition / discharge valve 3 are installed at both end...
