Pressure regulator

A pressure regulator assembly comprising:

• a housing having a chamber defined therein and an inlet and outlet both communicating with the chamber;
• a pressure responsive member interposed between the inlet and outlet for regulating fluid communication therebetween, at least a portion of the pressure responsive member being movable relative to the chamber in response to fluid pressure, the pressure responsive member including means for varying the freedom of movement thereof at different positions to allow freer movement of the pressure responsive member adjacent a shutoff position and a dampened range of movement adjacent a full open position;
• and
• means for altering the pressure at which the pressure responsive member moves relative to the chamber, said pressure altering means being adjustable as desired by an operator.

• means for altering the pressure at which the pressure responsive member moves relative to the chamber, said pressure altering means being adjustable as desired by an operator;
• and
• an external source of fluid pressure and a second pressure regulator receiving fluid pressure therefrom for controlling the pressure to the opening.
