<p>The invention relates to a compressed gas regulator comprising a body, an input coupling attached to the body for connecting the regulator to a compressed gas tank, an output coupling attached to the body for outputting the regulated gas, an expansion means for reducing the pressure of the gas coming from the input coupling at a predetermined pressure level towards the output coupling and an adjustment means mounted on the body and acting on the expansion means in order to determine the pressure level of the gas after expansion. The regulator comprises an adjustment means for adjusting the relative position of a scale and a reference mark, the scale and the reference mark being linked one to the body and the other to the adjustment means in order to mark the relative position of the adjustment means on the body. Moreover, the invention does not include means for providing a measured indication of the outlet pressure.</p> |
