摘要： A hydraulic control apparatus for an automatic transmission has a circulating oil supply passage that supplies circulating oil to a starting apparatus, a circulating oil discharge passage that discharges circulating oil from the starting apparatus, and a speed change mechanism oil supply passage that supplies oil to a speed change mechanism. The oil discharged from an oil pump is supplied to the starting apparatus and the speed change mechanism. A first flow rate changing device that can change the flow rate of the circulating oil is arranged in the circulating oil discharge passage. A first flow rate instructing portion output a command to the flow rate changing device to change the flow rate when the amount of oil discharged from the oil pump is low, and reduces the flow rate to the starting apparatus, which enables the hydraulic pressure necessary for shifting to be obtained in the speed change mechanism.

摘要： A circulation pressure is supplied to a starting device (2), and a working pressure that engages and disengages a lockup clutch (3) by the difference from the circulation pressure is regulated by a linear solenoid valve (10). A spool portion (12 1 ) of the linear solenoid valve (10 1 ) is provided with a first feedback oil chamber (12b) for feeding back the working pressure to a spool (12p), and a second feedback oil chamber (12a) for feeding back the circulation pressure to the spool (12p) in the direction opposite to that of the first feedback oil chamber (12p). A pressure-receiving area (A1 - A2) of the first feedback oil chamber (12b) and a pressure-receiving area (A1 - A2) of the second feedback oil chamber (12a) are set equal to each other in the spool (12p). Thus, an oil pressure acting force of the working pressure of the first feedback oil chamber and that of the circulation pressure of the second feedback oil chamber can be equal to each other, whereby engagement/disengagement control and slip control of the clutch can be accurately performed.
摘要翻译：向起动装置（2）供给循环压力，利用线性电磁阀（10）来调节使锁止离合器（3）与循环压力之差进行分离的工作压力。线性电磁阀（101）的阀柱部（121）具备用于将工作压反馈给阀柱（12p）的第一反馈油室（12b），和用于反馈工作压力的第二反馈油室（12a）沿与第一反馈油室（12p）相反的方向对阀芯（12p）的循环压力。第一反馈油室（12b）的受压面积（A1-A2）和第二反馈油室（12a）的受压面积（A1-A2）在卷轴12p中彼此相等）。因此，第一反馈油室的工作压力与第二反馈油室的循环压力的油压作用力可以彼此相等，由此可以精确地控制离合器的接合/分离控制和打滑控制执行。
