摘要： PROBLEM TO BE SOLVED: To provide a liquid flow path structure with a pressure regulating valve in a liquid flow path for well suppressing the generation of unpleasant abnormal sounds when regulating pressure in the liquid flow path structure. SOLUTION: The liquid flow path structure 13 with the pressure regulating valve 15 comprises a gas storage chamber 24 provided in a corner part 27 formed in a connection joint 19 located on the downstream side of the pressure regulating valve 15 for functioning as a vibration suppressing part. The gas storage chamber 24 is arranged at a position where ATF flowing from the upstream side into the corner part 27 collides. Pressure pulsation propagated together with the flow of the ATF is damped by the damper effect of the gas storage chamber 24. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a hydraulic control device capable of avoiding occurrence of a rapid deceleration state in a belt type continuously-variable transmission without adding a new solenoid valve. SOLUTION: The hydraulic control device is equipped with a fail-safe valve 305 capable of switching hydraulic pressure to be supplied to a primary pulley 41 between output hydraulic pressure of a gearshift hydraulic pressure control valve 301 and hydraulic pressure different from the output hydraulic pressure. The fail-safe valve 305 is switched to a fail position for supplying the different hydraulic pressure to the primary pulley 41 when there is possibility that a rapid deceleration state will occur, and is otherwise switched to a normal position for supplying the output hydraulic pressure of the gearshift hydraulic pressure control valve 301 to the primary pulley 41. The switchover of the fail-safe valve 305 is controlled by control hydraulic pressure of an ON-OFF solenoid (SL) 204 and control hydraulic pressure of a duty solenoid (DSU) 203.

摘要： PROBLEM TO BE SOLVED: To provide an automatic transmission in which the torque transmission efficiency with respect to an output shaft and the space efficiency around the output shaft are improved in the automatic transmission arranging a friction engagement device for hydraulically engaging behind a planetary gear unit in a transmission mechanism.
SOLUTION: In a transmission case 13, the rear end of an intermediate shaft 19 is interposed in a recess 31 formed in a front end of an output shaft 20, and the planetary gear unit G is arranged at the periphery of the intermediate shaft 19. A clutch C2 for hydraulically engaging is arranged at the position behind the planetary gear unit G and in front of the front end of the output shaft 20. Operating fluid is discharged from an apply oil passage 40 bored in the intermediate shaft 19 into a hydraulic chamber 27 of the clutch C2. Thereby the front end of the output shaft 20 can be reduced in diameter, and the clutch C2 can be arranged inside in the radial direction.
