PRESSURE REGULATOR FOR GASEOUS FUEL

摘要

PROBLEM TO BE SOLVED: To prevent uncomfortable feeling from being given by suppressing or eliminating loud noise when a pressure-reducing valve of a pressure regulator with compressed fuel taken as gaseous fuel of constant positive pressure has a small opening. SOLUTION: A partition member 21 having a through hole 23 for flowing compressed fuel into the pressure-reducing valve 11 is fitted into an inlet chamber 3 to change the natural frequency of the inlet chamber 3 to a different value. This prevents vibration generated when a valve body 12 has a small stroke and loud noise due to resonance frequency between the valve body 12 and a valve lever 10, which resonates with the inlet chamber 3.
