A pressure regulator has a valve tube assembly, a gas-input assembly, a first regulating assembly and a second regulating assembly. The gas storage device has a storage unit and the pressure regulator. By the first and the second regulating assemblies, the effect of adjusting down the gas pressure is achieved to maintain the safety of use. The pressure regulator is partially embedded in the gas storage unit to reduce the overall volume of the gas storage device. However, the high-pressure piston chamber of the valve tube assembly communicates with the outside of the gas storage unit through the high-pressure gas channel to maintain the normal operation of the elastic element in the high-pressure piston chamber.

A multi-stage pressure regulation system, device with enhanced thermal distribution for reducing the pressure of gas passing through a gas sample conditioning system. The device and method allow for automatic and/or manual configuration settings for regulating different types of gas having different profiles while still avoiding dew point dropout thereby ensuring accurate sample analysis at a downstream analyzer. The pressure regulating device includes a housing having a core, a vapor sample input port, a plurality of openings on an upper surface, a plurality of pressure regulating valves configured to reduce the pressure of a vapor sample, an assembly having a base and substantially central stem orthogonal to the base and extending axially therefrom, the stem being disposed within the core, and an adjunct for enhanced distribution of thermal energy from the heating device to the plurality of pressure regulating valves.

Example implementations relate to a pressure regulator assembly for a closed fluid loop of a CDU. The pressure regulator assembly has a cylinder having an internal volume, and first and second hollow pistons slidably connected to the cylinder to split the internal volume into a first volume portion having cooling fluid, a second volume portion having driver fluid, and a third volume portion having compressible matter. The first volume portion is fluidically connected to the closed fluid loop. The first hollow piston is reciprocated by the compressible matter to maintain operating pressure of the cooling fluid in the closed fluid loop. The second hollow piston is driven by the driver fluid in response to predefined pressure drop of the cooling fluid during predefined time period, to inject additional cooling fluid from the first volume portion into the closed fluid loop to restore pressure level of cooling fluid to operating pressure.
