  • Publication number: 20190146528
    Abstract: A gas pressure regulator comprises a high pressure inlet and a regulator mechanism which is arranged to receive high pressure gas via the high pressure inlet, and deliver gas at a regulated pressure to a regulated pressure outlet. The regulator comprises a regulator element and a rotatable member that rotates to move the regulator element, thereby adjusting the regulated pressure. A gauge arranged to receive high pressure gas and display a measured reading of the pressure of the high pressure gas is also provided along with a regulated pressure indicator which is arranged to display a regulated pressure value related to the degree of rotation of the rotary mechanism. The regulator mechanism has a gear chain between the rotatable member and the indicator so that it requires multiple rotations of the rotatable member to move the regulator element through its full range of movement.
