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.
