| Abstract: | The pressure regulator is one of the core units in space propulsion systems. The overall scheme design, structural characteristics, key technologies and achieved qualifications of the reverse unloading pneumatic pressure regulator with metal diaphragm are summarized. The key technology breakthrough achieved in the R＆D process is described. The verified results in the space flights testing indicate that the pressure regulator works well. Therefore, the research is significant for optimizing the structural parameters and reliable design of the regulator. |
