Abstract
A torque converter comprises a cover configured to receive an input torque and an impeller having an impeller shell non-rotatably connected to the cover. A piston is disposed axially between the cover and the impeller. The piston is configured to axially displace to selectively engage a clutch and a seal plate is disposed axially between the piston and the cover. The seal plate is sealed to the cover. A first chamber is formed at least in part by the cover, the seal plate, and the piston. A second chamber is formed at least in part by the piston and the impeller shell.
Claims21
A torque converter, comprising:
- a cover configured to receive an input torque;
- an impeller having an impeller shell non-rotatably connected to the cover;
- a piston disposed axially between the cover and the impeller, wherein the piston is configured to axially displace to selectively engage a clutch;
- and
- a seal plate disposed axially between the piston and the cover, wherein:
- the seal plate is sealed to the cover;
- a first chamber is formed at least in part by the cover, the seal plate, and the piston;
- and
- a second chamber is formed at least in part by the piston and the impeller shell.
(canceled)
A torque converter, comprising:
- a cover configured to receive an input torque;
- an impeller having an impeller shell non-rotatably connected to the cover;
- a clutch including a piston disposed axially between the cover and the impeller, wherein the piston is configured to axially displace for engagement of the clutch;
- a seal plate sealed to the cover and disposed axially between the piston and the cover;
- a first chamber formed at least in part by the cover, the seal plate, and the piston;
- and
- a second chamber formed at least in part by the piston and the impeller shell, wherein:
- in response to an increase of pressurized fluid in the first chamber relative to the second chamber, the piston is configured to axially displace to open the clutch;
- in response to an increase of pressurized fluid in the second chamber relative to the first chamber, the piston is configured to axially displace to close the clutch.
