<p>A regulator of the present invention includes: a body equipped with an inlet port and an outlet port; an inflow passage and an outflow passage which are formed in the internal of the body; a guide having an connecting passage for connecting the inflow passage and the outflow passage by sealing the inflow passage; a valve assembly having an orifice gap placed inside the guide; a cover to finish an opening of an end part of the body; a piston which is installed in a piston room formed at the body for functioning the pressure of inlet gas of the outflow passage and combined with the valve assembly; a spring interposed between the piston and the cover; and an auxiliary spring interposed between the body and the assembly of valve. Accordingly, the present invention can prevent an increase in the closing pressure which is caused by malfunction of the deviation from coaxiality and separation of each assembly forming the valve by allowing the valve assembly to be closed even if the deviation from coaxiality is in a bad condition or there is a gap between each component since the valve assembly is formed in a free joining method. The present invention also can reduce vibration of outlet pressure by operating the piston even in fine vibration of the outlet pressure since the outflow passage from which decompressed gas leaks out and the piston room are connected.</p> |
