Claim 17:
18. A variable pressure regulator having an axial dimension and a lateral dimension, the variable pressure regulator comprising:
a pressure regulator housing;
a pressure regulator assembly disposed within the pressure regulator housing, the pressure regulator assembly comprising a piston and a piston seat, the piston being movable along the axial dimension when the variable pressure regulator is in an operational state;
the piston seat comprising a floor, the floor comprising a proximal region;
the piston comprising a proximal end and a distal end, the proximal end being closer to the floor of the piston seat than the distal end along the axial dimension, the proximal region of the floor comprising that region of the floor closest to the proximal end of the piston along the axial dimension; and
the pressure regulator assembly further comprising an adjustment mechanism shaped and arranged to alter a resting axial distance intermediate the proximal end of the piston and the proximal region of the floor when the pressure regulator is in a resting state, wherein the adjustment mechanism is selected from a group consisting of a threaded adjustment mechanism and a snap-fit adjustment mechanism.
