Gas temperature reducing system for regulating delivery of a high-pressure gas

A system for regulated delivery of a high-pressure gas, comprising:

• a housing adapted to be coupled to a source of a high-pressure gas;
• a chamber disposed within said housing;
• a first flow path in said housing leading from the source of the high-pressure gas to said chamber;
• a flow restrictor disposed in said first flow path;
• an actuation valve disposed in said first flow path between said flow restrictor and said chamber, wherein the high-pressure gas flows through said flow restrictor only when said actuation valve is opened and wherein said flow restrictor slows the high-pressure gas passing there through;
• a second flow path in said housing leading from the source of the high-pressure gas to said chamber;
• a pressure regulator disposed in said housing;
• a third flow path in said housing providing fluid communication between said chamber and said pressure regulator;
• and
• a valve disposed in said second flow path, said valve sealing said second flow path when gas pressure at the source exceeds gas pressure in said chamber, and said valve opening said second flow path when the gas pressure at the source is balanced with the gas pressure in said chamber wherein the high-pressure gas flows to said pressure regulator via said third flow path.

A system for regulated delivery of pressurized oxygen gas, comprising:

• a chamber;
• a first flow path adapted to be coupled to a source of pressurized oxygen gas, said first flow path providing for transport of the pressurized oxygen gas from the source to said chamber;
• a flow restrictor disposed in said first flow path for slowing the pressurized oxygen gas transported along said first flow path to said chamber;
• a second flow path adapted to be coupled to the source of the pressurized oxygen gas, said second flow path providing for transport of the pressurized oxygen gas from the source to said chamber;
• a pressure regulator made at least partly from non-metallic materials;
• a third flow path providing fluid communication between said chamber and said pressure regulator;
• and
• a valve disposed in said second flow path, said valve sealing said second flow path when gas pressure at the source exceeds gas pressure in said chamber, and said valve opening said second flow path when the gas pressure at the source is balanced with the gas pressure in said chamber wherein the high-pressure gas flows to said pressure regulator via said third flow path.
