Claims

[Scope of utility model registration request]

A pressure regulator main body is provided with a primary inlet and a secondary outlet for carbon dioxide gas, and a valve seat is provided in a communication path between the inlet and the outlet of the main body and is biased toward the valve seat by a compression spring on the primary side. A diaphragm is disposed across the valve seat and opposed to the valve seat, and is biased toward the valve seat by a compression spring on the secondary side. In a small pressure regulator for carbon dioxide gas, which is provided with a valve connecting pin that extends freely and has a free end that contacts a diaphragm or a valve seat, a gas outlet that communicates a space on the diaphragm side with respect to the valve seat and a secondary side outlet. A small pressure regulator for carbon dioxide gas that has a heat pipe installed directly or indirectly on the diaphragm side of the passage.
