Abstract:
With the increasing of spacecraft working life, the design of traditional solenoid valves can not meet the requirement of space propulsion system. The design scheme of a long-life, high-credibility, non-friction S-spring valve is introduced in this paper. An S-spring suspended armature style component is adopted in the solenoid to eliminate the redundancy residual caused by sliding friction in the valve. At present, this design scheme has passed mechanics and thermal environment test, and endured a million times of working life cycle. It has entered into engineering application phase.
