    摘要： This invention provides a switch valve which can increase durability without causing driver discomfort at a time when a failure occurs. The switch valve has a spool is formed by a spool portion and a plunger which is arranged so as to freely abut against the spool portion. The switch valve also include a spool surrounding portion surrounding the spool and provided with a plurality of land portions. The spool selectively adopts a position at a normal, non-failure state and a position at a fail state. In the position at the normal state, at least one corner portion of the land in the plunger protrudes from an end portion of the corresponding land portion. Because a stepped wear portion is not formed on an inner peripheral surface of the land portion, foreign materials, such as wear powders or the like, do not enter a portion between an outer peripheral surface of the land and the inner peripheral surface of the land portion when the failure occurs.

    摘要： A hydraulic control device for an automatic transmission that can ensure power transmission when a failure occurs to the solenoid valve of the hydraulic control device, the hydraulic control device having a plurality of hydraulic servos for engaging and disengaging a plurality of friction engagement elements in accordance with the supply and discharge of a hydraulic pressure so as to prevent interlock from occurring to the transmission, a solenoid valve for generating a predetermined hydraulic pressure and supplying the predetermined hydraulic pressure to a hydraulic servo selected in correspondence with a target gear ratio and fail-safe means for supplying fail-safe hydraulic pressure to at least two hydraulic servos selected to attain an arbitrary gear ratio when a failure occurs to the solenoid valve and power transmission thereby becomes impossible. Further, the hydraulic control device has a plurality of solenoid valves for supplying the predetermined hydraulic pressure to the plurality of hydraulic servos and a shutoff valve, disposed between a hydraulic pressure source and one of the solenoid valves, for shutting off supply of hydraulic pressure to that one solenoid valve when hydraulic pressure to be supplied to the hydraulic servos selected in correspondence with the target gear ratio and hydraulic pressure to be supplied to the other hydraulic servos are generated.

    摘要： In a hydraulic control device, when a solenoid pressure from a linear solenoid valve is not supplied to a brake, which is normally not engaged at the same time as a brake, not to engage the brake, a switching valve is supplied with a line pressure as a signal pressure for establishing a blocked/discharge state in which supply of the solenoid pressure to the brake is blocked and a hydraulic pressure can be discharged from the brake. When the solenoid pressure is supplied to the brake to engage the brake, the switching valve is supplied with a modulator pressure, which is lower than the line pressure, as a signal pressure for establishing a communicated state in which the solenoid pressure can be supplied to the brake.
