摘要： PROBLEM TO BE SOLVED: To provide a hydraulic control device for an automatic transmission, which makes it possible to individually supply hydraulic pressure to, and release hydraulic pressure from, two hydraulic oil chambers and to reduce the number of solenoid valves, thereby permitting cost reduction and enabling the device to be made compact. SOLUTION: This hydraulic control device includes a first B-2 relay valve 24 changing over supply and discharge of hydraulic pressure to and from an inner oil chamber 45A, and a second B-2 relay valve 25 changing over supply and discharge of hydraulic pressure to and from an outer oil chamber 45B, is constructed to supply signal pressure P S2 of a solenoid valve S2 to an oil chamber 24a, an oil chamber 25a, and an oil chamber 25e, and changes over an input state of the signal pressure P S2 to the oil chamber 25e by a C-2 supply relay valve 23 to be changed over by signal pressure P S1 of a solenoid valve S1 for fail safe. It becomes possible to individually make a changeover of the first B-2 relay valve 24 by the solenoid valve S2 and a changeover of the second B-2 relay valve 25 by the solenoid valve S1.

摘要： PROBLEM TO BE SOLVED: To provide a solenoid valve avoiding wear of a sleeve outer periphery resulted from lateral pressure by making a direction of resultant force of the lateral force acting on a sleeve the same when output hydraulic pressure is output and when not output.SOLUTION: The solenoid valve includes a feedback port 34 and an output port 26 at a part opposite to an input port 37 relative to the axis of the sleeve 22, and the sleeve includes a recess 31 provided to form a feedback oil passage 28, a seal part 27 provided to enclose the feedback oil passage and seal leaking oil, and a lateral pressure reducing groove 30 formed to let the oil leaked from the feedback oil path through the seal part flow outside a valve section. The solenoid valve is configured so that the lateral pressure reducing groove lets out oil to make the direction of resultant force of the lateral force acting on the sleeve the same when the output hydraulic pressure is output and when not output, and avoids a defect that the sleeve has wear or the like.

摘要： PROBLEM TO BE SOLVED: To stably supply working oil to a lubricating portion without cooling the working oil by an oil cooler even when the oil cooler and a cooler input check valve are damaged and when a temperature of the working oil is low.
SOLUTION: When a hydraulic pressure of working oil supplied to an input port 1c of a cooler input check valve 1 becomes higher than a predetermined hydraulic pressure like when an oil cooler 2 and the like are damaged, a bypass valve 4 is operated to open, so as to supply the working oil at the input port 1c of the cooler input check valve 1 to a predetermined lubricating portion 5 via a bypass pipeline 16. Also, in a place where oil resistance of the working oil is large like in a cold district, the working oil is input to the other input port 1f of the bypass valve 4 via a solenoid valve 9, so that the bypass valve 4 is operated to open, to supply the working oil on the input port 1c side of the cooler input check valve 1 to a predetermined lubricating portion 5 via the bypass pipeline 16.

摘要翻译：要解决的问题：即使当油冷却器和冷却器输入止回阀被损坏以及工作油的温度低时，也可以通过油冷却器将工作油稳定地供给到润滑部分而不使工作油冷却。
解决方案：当油冷却器2等被损坏时，供给至冷却器输入止回阀1的输入口1c的工作油的液压变得高于预定的液压时，旁通阀4被操作以便将冷却器输入止回阀1的输入口1c处的工作油经由旁通管道16供给到预定的润滑部5。另外，在工作油的耐油性大的地方，如工作油通过电磁阀9输入到旁通阀4的另一个输入口1f，使旁通阀4开启，将工作油供给到输入口1c侧，冷却器输入止回阀1通过旁通管道16连接到预定的润滑部分5.版权所有：（C）2009，JPO＆INPIT
