Abstract:
A regulator for regulating outlet pressure of a fluid contained in a tank, comprising:a body having an axis;a first piston disposed in the body and having an end and a first bore, the first piston being movable in response to pressure in the tank when exposed to the pressure in the tank; anda second piston disposed in the body and having an end and a second bore, the second piston being movable toward and away from the end of the first piston in response to the outlet pressure;the ends of the first and second pistons being separated by a first distance to allow the fluid to flow out of the tank, through the first bore and then through the second bore, and the ends of the first and second pistons being positioned closer together than the first distance to inhibit flow out of the tank when the outlet pressure reaches a threshold;wherein the pistons have a common axis that is offset from the axis of the body.
