摘要

A gas pressure reducing regulator having a valve assembly with a slidable valve member containing a valve seat disposed within a valve chamber communicating with the inlet opening connection to a source of high inlet pressure through serially connected passageways having intersecting axes with an included angle of less than ninety degrees. The valve assembly also has a frustoconical tapered head juxtaposed relative to the valve seat such that upon loss of valve seat material the nozzle nestles into the seat to close off the valve.
