Fluid driver

Abstract

In a rotatable tube having an open end and a closed end, an aperture is disposed along a length of the tube and is associated with a blade configured to create a reduced pressure pocket within a fluid medium near the aperture. When the tube, the aperture and the blade rotate within the fluid medium, an input gas is drawn through the open end of the tube and into the fluid medium through the aperture.

1 . An fluid driver, comprising:
 a rotatable tube having an open end and a closed end;   an aperture disposed along a length of the tube; and   a blade associated with the tube and configured to create a reduced pressure pocket within a fluid medium near the aperture when the tube, the aperture and the blade rotate within the fluid medium, thereby drawing an input gas through the open end of the tube and into the fluid medium through the aperture.   
     
     
         2 . The fluid driver of  claim 1 , wherein the blade extends outwardly along an edge of the aperture. 
     
     
         3 . The fluid driver of  claims 1  or  2 , wherein the blade at least partially extends over the aperture. 
     
     
         4 . The fluid driver of  claims 1  or  2 , wherein the blade is circumferentially associated with the aperture. 
     
     
         5 . The fluid driver of  claim 1 , including multiple apertures disposed along the length of the tube, wherein each aperture has an associated blade. 
     
     
         6 . The fluid driver of  claim 1 , including a housing encompassing the aperture and the blade and partially disposed within the fluid medium, wherein the housing is positioned to trap foam formed as a result of the input gas entering the fluid medium through the aperture. 
     
     
         7 . The fluid driver of  claim 6 , including a gas separator coupled to the tube and positioned within the housing to rotatably contact the foam. 
     
     
         8 . The fluid driver of  claim 7 , wherein the gas separator comprises a wire. 
     
     
         9 . The fluid driver of  claims 6 ,  7  or  8 , wherein the housing includes a vent. 
     
     
         10 . The fluid driver of  claim 1 , wherein the fluid driver resides within a container housing the fluid medium. 
     
     
         11 . The fluid driver of  claim 10 , wherein when the container is open to the atmosphere, the fluid driver provides aeration, and when the container is closed to the atmosphere, the fluid driver provides aeration and compresses the input gas therein. 
     
     
         12 . The fluid driver of  claims 1 ,  10  or  11 , including multiple closed containers coupled to the tube in series with one another, wherein the tube is configured to selectively receive compressed gas from one closed container for subsequent injection into the fluid medium of the next closed container in the series. 
     
     
         13 . The fluid driver of  claim 12 , wherein the gas is increasingly compressed as it passes through subsequent closed containers in the series. 
     
     
         14 . The fluid driver of  claim 1 , wherein the fluid medium is relatively heavier than the gas. 
     
     
         15 . The fluid driver of  claim 1 , wherein the blade rotates in the same rotational direction as the tube. 
     
     
         16 . The fluid driver of  claim 1 , including a second blade coupled to a bushing disposed concentrically about the tube. 
     
     
         17 . The fluid driver of  claim 16 , wherein the bushing rotates in an opposite direction as the rotation of the tube. 
     
     
         18 . The fluid driver of  claim 16 , including a turbulence ring coupled to the bushing.
