Multi-vane device

Abstract

A device for varying the pressure of a gas. The device contains a rotatable disk with an axis of rotation, a top surface and a bottom surface; at least two vanes are radially connected to the rotatable disk. The device also contains a first stator with a first centerline disposed near said top surface of the rotatable disk, a second stator with a second center disposed near the bottom surface of said rotatable disk, and a third stator with a third centerline disposed above the rotatable disk. The axis of rotation of the rotatable disk is coincident with both the first centerline of said first stator, second centerline of second stator, and the third centerline of said third stator.

1 . A device for varying the pressure of a gas that contains a rotatable disk with an axis of rotation, a top surface and a bottom surface, at least two vanes radially connected to the rotatable disk, a first stator with a first centerline disposed near said top surface of said rotatable disk, a second stator with a second center disposed near said bottom surface of said rotatable disk, and a third stator with a third centerline disposed above said rotatable disk, wherein said axis of rotation of said rotatable disk is coincident with both said first centerline of said first stator, said second centerline of said second stator, and said third centerline of said third stator.  
   
   
       2 . The device as recited in  claim 1 , further comprising means for flowing gas through said rotatable disk in a first direction, thereby producing a first gas flow.  
   
   
       3 . The device as recited in  claim 2 , further comprising means for flowing said first gas flow past said first stator, thereby producing a second gas flow.  
   
   
       4 . The device as recited in  claim 3 , further comprising means for longitudinally flowing said second gas flow through said third stator in a second direction that is opposite to said first direction, thereby producing a third gas flow.  
   
   
       5 . The device as recited in  claim 4 , further comprising means for flowing said third gas flow radially and downwardly past said second stator.  
   
   
       6 . The device as recited in  claim 1 , wherein said vanes are radially and equidistantly connected to the periphery of said rotatable disk.  
   
   
       7 . The device as recited in  claim 1 , wherein at least 3 of said vanes are radially and equidistantly connected to the periphery of said rotatable disk.  
   
   
       8 . The device as recited in  claim 1  wherein at least 8 of said vanes are radially connected to the periphery of said rotatable disk.  
   
   
       9 . The device as recited in  claim 1 , wherein at least 16 of said vanes are radially connected to the periphery of said rotatable disk.  
   
   
       10 . The device as recited n  claim 1 , wherein at least one vane is radially connected to said first stator.  
   
   
       11 . The device as recited in  claim 10 , wherein at least one vane is radially connected to said second stator.  
   
   
       12 . The device as recited in  claim 11 , wherein at least one vane is radially connected to said third stator.  
   
   
       13 . The device as recited in  claim 12 , wherein said first stator has a substantially hemispherical cross-sectional shape.  
   
   
       14 . The device as recited in  claim 13 , wherein said second stator has a substantially hemispherical cross-sectional shape.  
   
   
       15 . The device as recited in  claim 14 , wherein said third stator has a substantially rectilinear cross-sectional shape.  
   
   
       16 . The device as recited in  claim 14 , wherein said device comprises flow splitter disposed between said rotatable disk and said third stator.  
   
   
       17 . The device as recited in  claim 16 , wherein said flow splitter is a ring.  
   
   
       18 . The device as recited in  claim 1 , wherein said first stator comprises an arcuate channel whose depth varies along its length.  
   
   
       19 . The device as recited in  claim 18 , wherein said second stator comprises an arcuate channel whose depth varies along its length.
