Device for directing the flow of a fluid using a pressure switch
First Claim
1. 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.

Abstract
A device for directing the flow of a fluid comprises: 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, and wherein the pressure switch is positioned adjacent to the pressure source. According to an embodiment, depending on at least one of the properties of the fluid, the fluid that flows into the pressure pocket changes. In one embodiment, the change is the fluid increasingly flows into the pressure pocket. In another embodiment, the change is the fluid decreasingly flows into the pressure pocket. According to another embodiment, a flow rate regulator comprises: the device for directing the flow of a fluid; a second fluid passageway; a third fluid passageway; and a fourth fluid passageway.

12. A device for directing the flow of a fluid, wherein the fluid has a plurality of properties, the device comprises:
-
a pressure pocket; a first fluid passageway; a second fluid passageway; a third fluid passageway; a fourth fluid passageway, wherein the second fluid passageway branches into the third and fourth fluid passageways; a pressure source; and a pressure switch, wherein the pressure source is located between the first fluid passageway and the pressure switch, wherein the first fluid passageway operationally connects at least the pressure pocket and the pressure source, wherein as at least one of the properties of the fluid changes, the amount of fluid flowing in the first fluid passageway changes; wherein as the amount of fluid flowing in the first fluid passageway changes, the pressure of the pressure source changes; and wherein as the pressure of the pressure source changes, the pressure switch directs the fluid to increasingly flow into the third fluid passageway or the fourth fluid passageway. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. 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 amount of fluid that flows into the pressure pocket changes whereby; (a) as the flow rate of the fluid in the second fluid passageway changes, the amount of fluid that flows into the pressure pocket changes inversely; (b) as the viscosity of the fluid in the second fluid passageway changes, the amount of fluid that flows into the pressure pocket changes similarly;
or(c) as the density of the fluid in the second fluid passageway changes, the amount of fluid that flows into the pressure pocket inversely changes, wherein the change in the amount of fluid that flows in the pressure pocket causes a change in the pressure from the pressure source, wherein as the pressure from the pressure source increases, the pressure switch directs the fluid to increasingly flow into the fourth fluid passageway, and wherein as the pressure from the pressure source decreases, the pressure switch directs the fluid to increasingly flow into the third fluid passageway. - View Dependent Claims (45)
