Abstract

A torque converter including a turbine, a vibration damper, a cover, the cover having blades, and a clutch pack, the blades increasing a fluid flow toward or away from the clutch pack.

Claims (23)

1. A torque converter comprising:

a turbine;

a vibration damper;

a cover, the cover having blades; and

a clutch pack, the blades increasing a fluid flow toward the clutch pack,

wherein the blades face axially inward toward the clutch pack.

2. The torque converter as recited in claim 1 further comprising a primary fluid flow bypassing the clutch pack and a secondary fluid flow passing through the clutch pack.

3. The torque converter as recited in claim 2 wherein the primary fluid flow is between the turbine and vibration damper.

4. The torque converter as recited in claim 1 wherein the blades increase fluid flow away from the clutch pack.

5. The torque converter as recited in claim 1 wherein the clutch pack has clutch linings.

6. A torque converter comprising:

a turbine;

a vibration damper;

a cover, the cover having blades; and

a clutch pack, the blades increasing a fluid flow away from the clutch pack,

wherein the blades face axially outward away from the clutch pack.

7. The torque converter as recited in claim 6 further comprising a primary fluid flow bypassing the clutch pack and a secondary fluid flow passing through the clutch pack.

8. The torque converter as recited in claim 7 wherein the primary fluid flow is between the turbine and vibration damper.

9. The torque converter as recited in claim 6 wherein the blades increase fluid flow toward the clutch pack.

10. The torque converter as recited in claim 6 wherein the clutch pack has clutch linings.

11. A method for operating a torque converter comprising:

directing a primary torque converter fluid flow, the fluid flow bypassing a lock-up clutch pack; and

using blades connected to a cover of the torque converter to increase a secondary flow off of the primary flow to pass through the clutch pack, the blades facing axially inward toward the clutch pack or axially outward away from the clutch pack.
