Abstract

An apparatus for mixing fluids includes a housing which is mounted in line with a conduit carrying a primary fluid. A deformable member is mounted in the housing and an inlet conduit carrying a secondary fluid communicates with the deformable member. An adjustment knob adjusts the width of the deformable member, thereby adjusting the venturi effect created by the deformable member in the flow of primary fluid and adjusting the flow of secondary fluid which flows into the deformable member and is induced out of the deformable member through a plurality of holes to mix with the primary fluid.

Claims

1. A fluid inductor apparatus comprising:

a housing comprising;

primary fluid inlet means;

primary fluid outlet means;

secondary fluid inlet means;

hollow wedge shaped means having opposite ends disposed in said housing between said primary fluid inlet means and said primary fluid outlet means, said hollow wedge shaped means comprising a plurality of pivotable side panels, at least one of said side panels having a plurality of holes formed therein proximate to said primary fluid outlet means; and

adjustment means, comprising;

a pair of guide pins projecting from opposite ones of said side panels at one end of said hollow wedge shaped means, and

control means coacting with the pair of guide pins for adjusting the distance between said guide pins for deforming said hollow wedge shaped means to adjust the width thereof, said secondary fluid inlet means communicating with said hollow wedged shaped means for inducing secondary fluid to flow into said hollow wedge shaped means and through said plurality of holes into said housing.

2. The fluid inductor apparatus according to claim 1, wherein said wedge shaped means comprises four side panels.

3. The fluid inductor apparatus according to claim 2, wherein said four side panels form a diamond shaped configuration.

4. The fluid inductor apparatus according to claim 2, wherein said control means comprises:

guide plate means having a V-shaped slot arrangement said guide pins riding in said V-shaped slot arrangement.

5. The fluid inductor apparatus according to claim 1, further comprising hinge means connecting adjacent ones of said pivotable side panels.

6. The fluid inductor apparatus according to claim 1, wherein said control means comprises:

guide plate means having a first V-shaped slot arrangement; and

motion transmission plate means having a second V-shaped slot arrangement with said guide pins projecting through said first and second slot arrangements in said guide plate means and said motion transmission plate means.

7. The fluid inductor apparatus according to claim 6, wherein said control means further comprises:

a pin projecting from said motion transmission plate means;

adjustment plate means having a spiral groove with said transmission plate means pin riding in said spiral groove;

drive connection means extending from said adjustment plate means through said housing; and

adjustment knob means on said housing connected to said drive connection means for rotation of said adjustment plate means.

8. The fluid inductor apparatus according to claim 6, wherein said hollow wedge shaped means comprises a plurality of top edges, said guide plate means being disposed to cover said hollow wedge shaped means.

9. The fluid inductor apparatus according to claim 6, wherein said guide plate means further comprises an aperture said secondary fluid inlet means projecting into said aperture.

10. The fluid inductor apparatus according to claim 6 wherein said first V-shaped slot arrangement in said guide plate means has a relatively wider portion, said first slot arrangement relatively wider portion being disposed proximate to said primary fluid outlet means, and said second V-shaped slot arrangement in said motion transmission plate means has a relatively wider portion, said second slot arrangement relatively wider portion being disposed proximate to said primary fluid inlet means.

11. The fluid inductor apparatus according to claim 6, wherein said first V-shaped slot arrangement in said guide plate means has a relatively wider portion, said first slot arrangement relatively wider portion being disposed proximate to said primary fluid inlet means, and said second V-shaped slot arrangement in said motion transmission plate means has a relatively wider portion, said second slot arrangement relatively wider portion being disposed proximate to said primary fluid outlet means.
