Attorney, Agent or Firm:
A fluid exchanger apparatus for exchanging a first fluid with a second fluid in varying proportions and comprising fluid exhaust for exhausting such first fluid along a predetermined exhaust flow path, fluid inlet for inducting such second fluid along a predetermined inlet flow path, transfer duct extending around a curved flow path, the path essentially defining a path plane, from the exhaust flow path to the inlet flow path, and providing a smoothly curved fluid flow path therebetween, at least a movable portion of the duct being movable relative to the fluid exhaust, the movable portion being rotatable about any axis except an axis perpendicular to the curve plane whereby rotation of the movable portion establishes and interrupts fluid flow connection between the fluid exhaust and the fluid inlet, and, power operator for moving the movable portion relative to the fixed portion into a plurality of different positions, whereby the first fluid may be mixed with the second fluid in varying proportions. |

DETAILED DESCRIPTION What is claimed is: 1.
A fluid exchanger apparatus for exchanging a first fluid with a second fluid in varying proportions comprising; fluid exhaust means for exhausting such first fluid along a predetermined exhaust flow path; fluid inlet means for inducting such second fluid along a predetermined inlet flow path; transfer duct means extending around a curved flow path, said path essentially defining a path plane, from said exhaust flow path to said inlet flow path, and providing a smoothly curved fluid flow path therebetween, a movable duct portion of said transfer duct means, said duct portion being movable relative to the fluid exhaust means and to said fluid inlet means, between a transfer position in which fluid transfer takes place from said fluid exhaust means to said fluid inlet means, and a disconnect position in which fluid is exhausted by said exhaust and fluid is taken in by said inlet independently of each other, and, duct movement means for moving said movable portion between said positions and into a plurality of different locations intermediate said positions, whereby said first fluid may be mixed with said second fluid in varying proportions.
2.
A fluid exchanger apparatus as claimed in claim 1 wherein said fluid exhaust means comprises power operated means for exhausting said first fluid and a housing means defining an exhaust opening means, and wherein said fluid inlet means comprises power operated means for inducting said second fluid and a housing means defining an inlet opening means, and wherein said exhaust opening means and said inlet opening means communicate with opposite ends of said transfer duct means.
3.
A fluid exchanger apparatus as claimed in claim 2 wherein said movable portion of said transfer duct means comprises a curved duct, curved through substantially 90.
degree.
, and having one end rotatably mounted in registration with one of said opening means, and having said other end movable about a predetermined swing axis, and wherein said transfer duct means also defines a fixed portion comprising a curved duct curved about an arc of generally 90
