Hydrogen compressor valve
The air valve is mainly composed of valve seat, valve cover (lift limiter), valve plate and spring (mesh valve and buffer plate and lift pad). The valve spring is made of stainless and acid resistant steel wire, which has high corrosion resistance and fatigue resistance, and can significantly improve the service life of the valve.
The oil scraper is mainly composed of gland, shell (or oil scraper box), oil scraper ring and tension spring. The oil scraper ring is a plane three piece straight opening type, made of tin bronze. The oil return hole is set under the shell (or oil scraper box), which can flow the oil scraped back to the oil pool of the fuselage through the oil return hole.
