| 20090045023 | Torque converter damper flange with turbine centering feature - A torque converter including a turbine, an output shaft, and a damper having at least one cover plate radially fixed to the turbine, a flange driven by the damper and non-rotatably connected to the output shaft, the flange having an axially extending surface centering the cover plate. | 02-19-2009 |
| 20090051087 | Damper with two-piece plate configuration - A damper for a torque converter, including: a first plate with at least one first opening; a second plate with at least one second opening; and at least one first spring disposed in the at least one first and second openings and including: a radially inward portion in contact with the at least one first opening; and first and second radially outward ends in contact with first and second sides of the at least one second opening and free of contact with the first plate. In one embodiment, the at least one first opening includes third and fourth sides and the radially inward portion includes first and second radially inward ends in contact the third and fourth sides. In another embodiment, the third and fourth sides are free of contact with the second plate. | 02-26-2009 |
| 20090071785 | Torque converter with reverse - A torque converter including: a turbine; a first stator; a first interlocking clutch; and a second interlocking clutch. In a first operating mode, to enable rotation of the turbine in a first direction, the first clutch is for engaging with the turbine and is engageable with an input shaft of a transmission and the second clutch is for engaging with the first stator and is engageable with a fixed shaft of the transmission. In a second operating mode, to enable rotation of the first stator in a second direction, opposite the first direction, the first clutch is for engaging with the first stator and is engageable with the input shaft and the second clutch is for engaging with the turbine and is engageable with the fixed shaft. | 03-19-2009 |
| 20090127050 | Normally closed three pass multi-function torque converter - A multi-function torque converter, including a pump clutch, and a resilient element arranged to close the pump clutch during operation of the torque converter in a torque converter mode. In one embodiment, the resilient element is arranged to close the pump clutch during operation of the torque converter in lock-up mode. In one embodiment, the torque converter includes a torque converter clutch. In one embodiment, the pump clutch and the torque converter clutch are closed during operation of the torque converter in a lock-up mode. | 05-21-2009 |
| 20090157272 | Four-passage multifunction torque converter - A torque converter including: an impeller clutch arranged to transmit, when closed, torque from a first cover for the torque converter to a shell for an impeller; a lock-up clutch arranged to transmit, when closed, torque from a second cover for the torque converter to an output hub; a release chamber for the impeller clutch, connected to a first channel; an apply chamber for the impeller clutch, connected to a second channel; an apply chamber for the lock-up clutch, connected to a third channel; and a torus connected to a fourth channel. The second, third, and fourth channels open to a space including a longitudinal axis for the torque converter and the space is arranged to receive an input shaft for a transmission. The first channel is arranged to connect to a line in a pump housing for a transmission. | 06-18-2009 |
| 20090159387 | Ratchet one way clutch with hardened blocking plate - A one-way clutch, including: a first annular element; a second annular element arranged to lockingly engage with the first element for relative rotation of the second element, with respect to the first annular element, in a first rotational direction; a third annular element at least partly rotatable about the axis and axially disposed between the first and second elements; and a fourth annular element at least partly rotatable about the axis and including a radially disposed body and an axial protrusion extending from the body and connected to the third element. The axial protrusion forms a portion of a space arranged to at least partially enclose fluid to dampen energy associated with the locking engagement of the first and second annular elements, and the first or second element is axially disposed between the third and fourth elements. | 06-25-2009 |
| 20100197412 | TORQUE CONVERTER LEAF SPRING CONNECTIONS - A connection for a torque converter including a cover, a piston plate, and at least one leaf spring having a first portion with a resilient segment and a second portion rotationally connected to one of the cover or the piston plate. The other of the cover or the piston plate comprises a first protrusion and the resilient segment grips the first protrusion. In an example embodiment, the second portion is riveted to the one of the cover or the piston plate. In an example embodiment, the one of the cover or the piston plate includes a second protrusion and the second portion includes a resilient segment that grips the second protrusion. | 08-05-2010 |
| 20110162718 | ROTATABLE FLANGE FOR A WATER MONITOR - A water monitor. A flange assembly has a stationary portion, a rotatable portion disposed in the stationary portion, and a duct extending through the stationary and rotatable portions. A water-driven turbine has a rotatable water wheel in communication with the duct and an output shaft coupled to the water wheel. Fluid flowing through the duct causes the water wheel to rotate, the rotation of the water wheel causing the output shaft to rotate. An output crank, a first linkage, a rocker arm, and a second linkage comprising a first linkage member and a second linkage member are operable by the output shaft to convert the rotating motion of the output shaft to an oscillatory motion. Fluid exiting the duct is distributed by the rotatable portion in a determinable oscillatory pattern. | 07-07-2011 |
