Device for directing the flow of a fluid using a pressure switch

A device for directing the flow of a fluid comprising:

• a pressure pocket;
• a first fluid passageway;
• a pressure source;
• and
• a pressure switch,
• wherein the first fluid passageway operationally connects at least the pressure pocket and the pressure source,
• wherein the pressure switch is positioned adjacent to the pressure source,
• wherein a desired flow rate of a fluid is predetermined, and when the flow rate of the fluid in a second fluid passageway decreases below the predetermined flow rate, the fluid increasingly flows into the pressure pocket compared to when the flow rate of the fluid in the second fluid passageway increases above the predetermined flow rate.

A flow rate regulator comprises:

• a device for directing the flow of a fluid comprising:
• (i) a pressure pocket;
• (ii) a first fluid passageway;
• (iii) a pressure source;
• and
• (iv) a pressure switch,
• wherein the first fluid passageway operationally connects at least the pressure pocket and the pressure source, and
• wherein the pressure switch is positioned adjacent to the pressure source,
• a second fluid passageway;
• a third fluid passageway;
• and
• a fourth fluid passageway,
• wherein the second fluid passageway branches into the third and fourth fluid passageways,
• wherein as at least one of the properties of the fluid changes, the fluid that flows into the pressure pocket changes.
