1. A method of maintaining a pressure within a supply tank, comprising:
- measuring one or more output flows from the supply tank;
determining whether one or more input flows to the supply tank balance the one or more output flows; and
when the one or more input flows to the supply tank do not balance the one or more output flows, modifying at least one of the one or more input flows to balance the one or more output flows, thereby maintaining the pressure within the supply tank.

Abstract
System and method for providing a constant pressure of a gas or a fluid. The method includes measuring one or more output flows from a supply tank and determining whether one or more input flows to the supply tank balance the one or more output flows. The method also includes modifying at least one of the one or more input flows to balance the one or more output flows when the one or more input flows to the supply tank do not balance the one or more output flows, thereby maintaining the pressure within the supply tank.

7. A system, comprising:
-
a supply tank; and
a controller configured to;
measure one or more output flows from the supply tank;
determine if one or more input flows to the supply tank balance the one or more output flows; and
if the one or more input flows to the supply tank do not balance the one or more output flows, modify at least one of the one or more input flows to balance the one or more output flows, thereby maintaining a pressure within the supply tank. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of maintaining a constant pressure in a supply vessel, the method comprising:
-
providing one or more input flows to the supply vessel;
providing one or more output flows from the supply vessel; and
if the one or more output flows from the supply vessel are greater than the one or more input flows to the supply vessel, diverting at least a first portion of at least one of the one or more input flows from the supply vessel to a buffer tank. - View Dependent Claims (14, 15)

16. A system, comprising:
-
a supply tank with one or more output flows and one or more input flows;
a buffer tank; and
a valve positioned between the supply tank and the buffer tank, wherein the valve is configured to divert at least a first portion of at least one of the one or more input flows from the supply vessel to a buffer tank if the one or more output flows from the supply vessel are greater than the one or more input flows to the supply vessel. - View Dependent Claims (17, 18)

19. A method of maintaining a constant pressure in a supply vessel, the method comprising:
-
providing one or more input flows to the supply vessel;
providing one or more output flows from the supply vessel; and
if the one or more output flows from the supply vessel are greater than the one or more input flows to the supply vessel, actuating a piston to decrease the volume of the supply vessel, thereby maintaining the constant pressure in the supply vessel. - View Dependent Claims (20, 21, 22, 23)

24. A system, comprising:
-
a supply tank with one or more output flows and one or more input flows;
a piston; and
a control mechanism for the piston configured to actuate the piston to decrease the volume of the supply vessel if the one or more output flows from the supply vessel are greater than the one or more input flows to the supply vessel, thereby maintaining the constant pressure in the supply vessel. - View Dependent Claims (25, 26, 27, 28)

29. A method of providing an input flow, comprising:
-
flowing a first stream of a gas from a first source at a first fixed flow rate;
flowing a second stream of the gas from the first source to a buffer tank at a second fixed flow rate;
flowing an output stream of the gas from the buffer tank to an oscillating valve;
combining the first stream of the gas with a third stream of the gas to form the input flow; and
actuating the oscillating valve during an oscillation cycle to change a flow rate of the third stream of the gas to maintain a desired flow rate of the input flow. - View Dependent Claims (30, 32)

33. A system, comprising:
-
a buffer tank;
a first stream of a gas flowing from a first source at a first fixed flow rate;
a second stream of the gas flowing from the first source to the buffer tank at a second fixed flow rate;
an output stream of the gas flowing from the buffer tank to an oscillating valve;
a connection combining the first stream of the gas with a third stream of the gas to form an input flow; and
a control mechanism configured to actuate the oscillating valve during an oscillation cycle to change a flow rate of the third stream of the gas to maintain a desired flow rate of the input flow. - View Dependent Claims (34, 35)
