| 20090038430 | ACTUATOR, RANGE CHANGEOVER DEVICE FOR AUTOMATIC TRANSMISSION, AND PARKING DEVICE - An actuator for a state changeover element that is actuated in a manner interlocking with the tilting of a tilt member is provided. The actuator is equipped with a rotational power generating portion, an output shaft coaxially and integrally rotatably coupled to a tilt spindle of the tilt member to output a rotational power generated by the rotational power generating portion, a casing that covers the actuator and having an opening for exposing one axial end side of the output shaft to an outside. The actuator is further equipped with a rotational angle limiting unit provided between the output shaft and a wall portion of the casing radially facing the output shaft to physically limit a rotational angle of the output shaft. A range changeover device for an automatic transmission equipped with this actuator and a parking device equipped with this actuator are provided. | 02-12-2009 |
| 20100082209 | HYDRAULIC CONTROL DEVICE FOR AUTOMATIC TRANSMISSION - A hydraulic control device for an automatic transmission that includes a fail-safe function to establish a fail-safe traveling state where a predetermined shift speed is established, and a fail-safe stopping state where the primary pressure to all of the hydraulic servos is cut-off when a failure occurs. The hydraulic control device is able to switch between the fail-safe traveling state and the fail-safe stopping state even after a failure occurs, thereby enhancing a limp-mode function. | 04-01-2010 |

| 20100081546 | HYDRAULIC CONTROL DEVICE FOR MULTI-SPEED AUTOMATIC TRANSMISSION - A hydraulic control device for a multi-speed automatic transmission includes friction engagement elements, several hydraulic servos that engage and release the friction engagement elements, solenoid valves for engagement control, and a sorting switch valve that allocates engagement pressure from at least one of the solenoid valves for engagement control to two of the hydraulic servos. The sorting switch is switched between a first position that supplies engagement pressure to one of the two hydraulic servos in at least a Reverse, non-drive range and a specific Forward gear range, and a second position that supplies engagement pressure to the two hydraulic servos in other than the Forward range. The hydraulic control device supplies the engagement pressure to the two hydraulic servos when an all-solenoids-off failure occurs and the sorting switch is in the second position, and cuts off a source pressure to all solenoid valves when an all-solenoids-off failure occurs while the sorting switch valve is in the first position. | 04-01-2010 |
