Gas Regulator Internal Vent Limiting Device

A vent assembly for a pressure regulator, the vent assembly comprising:

• a diaphragm defining a main relief opening;
• and
• a vent limiting component positioned within the main relief opening, the vent limiting component including:
• an upper portion, and
• a lower portion positioned circumferentially about the upper portion, the lower portion including a base extending in a radial direction from the upper portion, a sidewall extending at least partially in the radial direction from the base, and a flange that extends in the radial direction from the sidewall,
• wherein the base defines an orifice extending therethrough that fluidly couples a bottom surface of the diaphragm with an upper surface of the diaphragm.

A pressure regulator comprising:

• a diaphragm having an inner edge, the inner edge defining a main relief opening;
• a vent limiting component positioned within the main relief opening and adjacent to an upper side of the diaphragm about the inner edge;
• a relief valve stem positioned adjacent to a lower side of the diaphragm about the inner edge;
• and
• a main spring configured to provide a force to the vent limiting component to removably secure the vent limiting component to the diaphragm.
