摘要： An oil pressure control apparatus for an automatic transmission configured with an oil pressure servo that engages and disengages a friction engagement element. The friction element is engaged by first and second hydraulic oil chambers that individually provide low torque, and can provide a higher torque when working in combination. A failure solenoid valve outputs a signal when a failure occurs to stop oil pressure to an oil pressure servo. Valves are configured to determine whether oil pressure is supplied to or discharged from the first and second hydraulic oil chambers. A switching valve is switched on the basis of the failure signal, and an oil pressure can be individually supplied to and discharged from the first and second hydraulic oil chambers based on the status of the switching solenoid valve and the signal from the failure solenoid valve.

摘要： A hydraulic control device used in an automatic transmission includes an oil pump, a working pressure regulating portion, a first lubricant supply passage, a lockup switch mechanism, and a second lubricant supply passage. The oil pump is driven in accordance with rotation of a driving source. The working pressure regulating portion regulates a working pressure based on an oil pressure generated by the oil pump. The first lubricant supply passage supplies a back pressure of the working pressure to a lubricant passage. The lockup switch mechanism turns on/off a lockup clutch of the automatic transmission by switching a supply/discharge path of the working pressure to/from a fluid transmission apparatus of the automatic transmission. The second lubricant supply passage supplies the working pressure to the lubricant passage and is disconnected when a lockup clutch of the automatic transmission is turned on by the lockup switch mechanism.

摘要： A hydraulic control apparatus of an automatic transmission including a switching portion which, at the same time as a reverse range pressure oil passage and a discharge delay oil passage which delays an oil pressure output are connected, causes the reverse range pressure oil passage and discharge delay oil passage, by switching between the two, in order to communicate with a hydraulic servo. The switching portion causes the hydraulic servo and discharge delay oil passage to communicate when a manual valve is switched to an N range, and causes the hydraulic servo and reverse range pressure oil passage to communicate when the manual valve (MV) is switched to a D range or an R range. Because of this arrangement, it is difficult for oil, when discharged from the hydraulic servo, to drain at an R-N switching time, and it is easy for oil to drain in the D range or the like.
