Pressure regulator
First Claim
1. A regulator for regulating outlet pressure of a fluid supplied to the regulator from a fluid source, the regulator comprising:
- a body having an inlet;
a pressure regulating chamber disposed in the body; and
a high pressure fluid circuit extending between the inlet and the pressure regulating chamber for transmitting the fluid from the inlet to the pressure regulating chamber, the high pressure fluid circuit including a longitudinally extending high pressure passage that extends longitudinally away from the inlet and beyond the pressure regulating chamber.

Abstract
A regulator for regulating outlet pressure of a fluid supplied to the regulator from a fluid source includes a body having an inlet, and a pressure regulating chamber disposed in the body. A high pressure fluid circuit extends between the inlet and the pressure regulating chamber for transmitting the fluid from the inlet to the pressure regulating chamber. The high pressure fluid circuit includes at least two longitudinally extending high pressure passages in fluid communication with each other. One longitudinally extending high pressure passage transmits the fluid in a first direction, and another longitudinally extending high pressure passage transmits the fluid in a second direction different than the first direction.

a first piston having a first bore and an end disposed proximate the pressure regulating chamber, the first piston being movable in response to pressure of the fluid supplied to the regulator;
a second piston having a second bore and an end disposed proximate the pressure regulating chamber, 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 from the fluid source, through the first bore, 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 from the fluid source when the outlet pressure reaches a threshold;
wherein the body has a first axis, and the pistons have a common second axis offset from the first axis.

6. A regulator for regulating outlet pressure of a fluid supplied to the regulator from a fluid source, the regulator comprising:
-
a body having an inlet;
a pressure regulating chamber disposed in the body; and
a high pressure fluid circuit extending between the inlet and the pressure regulating chamber for transmitting the fluid from the inlet to the pressure regulating chamber, the high pressure fluid circuit including at least two longitudinally extending high pressure passages in fluid communication with each other, wherein one longitudinally extending high pressure passage transmits the fluid in a first direction, and another longitudinally extending high pressure passage transmits the fluid in a second direction different than the first direction. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A regulator for regulating outlet pressure of a fluid contained in a tank, the regulator comprising:
-
a body having an inlet adapted to be in fluid communication with the tank;
a pressure regulating chamber disposed in the body;
a high pressure fluid circuit extending between the inlet and the pressure regulating chamber for transmitting the fluid from the inlet to the pressure regulating chamber, the high pressure fluid circuit including at least two longitudinally extending high pressure passages in fluid communication with each other, wherein one longitudinally extending high pressure passage transmits the fluid in a first direction, and another longitudinally extending high pressure passage transmits the fluid in a second direction different than the first direction;
a first piston having an end disposed proximate the pressure regulating chamber, the first piston being movable in response to pressure in the tank when exposed to the pressure in the tank; and
a second piston having an end disposed proximate the pressure regulating chamber, 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, 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. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
