<p><P>PROBLEM TO BE SOLVED: To provide a pressure regulator constituted so as to secure an excellent pressure regulating function by preventing the pressure regulating function from being affected by the connecting operation of a connecting tool by the pressure regulator comprising a pressure regulating mechanism and a connector and to stop the reverse flow of fluid caused by attaching/detaching operations of the connecting tool. <P>SOLUTION: The pressure regulator comprises the connector 2 to which a supply connecting tool 3 supplying a pressurized fluid to a main body part 11 incorporating the pressure regulating mechanism 5 is connected. The connector 2 comprises a link member 544 openably operating a valve mechanism 6 according to the connecting operation of the supply connecting tool 3. The pressure regulating mechanism 5 comprises a pressure regulating valve 55 operated according to the deviation of a diaphragm 52 to regulate the pressurized fluid to a secondary pressure. The link member 544 is formed separately from the pressure regulating valve 55. Two check valves 56 and 57 for stopping the reverse flow of fluid are provided to the inside and outside of the pressure regulating valve 55. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
