摘要： A fluid pressure control device controls input and output of a fluid pressure to and from a fluid chamber in a device that transfers power from a motor via working fluid in the chamber, the chamber being partitioned into engagement and disengagement oil chambers by a lock-up clutch. A signal pressure output valve performs pressure regulation to output a signal pressure. The control device includes a control valve connected to an output source flow passage leading to an output source of the fluid pressure, and a control unit controlling the signal pressure output valve so the control valve establishes a first state when the lock-up clutch is turned off, establishes a third state when the lock-up clutch is turned on, and establishes a second state so the working fluid can be confined in the disengagement oil chamber when the lock-up clutch is switched on.

摘要： A hydraulic pressure control apparatus includes a primary regulator valve that regulates a pressure discharged from an oil pump to form a line pressure that is used as an original pressure for a hydraulic pressure that is supplied to each element, and a secondary regulator valve that regulates a hydraulic pressure downstream of the primary regulator valve to form a secondary pressure. Two pilot pressures (first modulator hydraulic pressure, control hydraulic pressure from a duty solenoid) are supplied to the secondary regulator valve. The secondary regulator valve is configured in such a manner that when one of the pilot pressures changes, a change in the one of the pilot pressures is absorbed by the other pilot pressure.

摘要： By pouring, by means of pressure, melted liquid of magnesium or magnesium alloy into a hollow portion which is formed using a casting mold, a valve body where a channel groove for hydraulic oil for use in a speed change operation of the automatic transmission is formed. In the above, the channel grove for the hydraulic oil is formed due to a convex portion which is formed on the mold so as to project into the hollow portion. As the magnesium has small heat capacity, variation of the temperature of the mold during the cooling and heating cycle can be suppressed. Moreover, as the magnesium melted liquid has no reactivity with respect to the casting mold, the convex portion is not deteriorated. This allows employment of a mold having a thinner convex portion formed thereon, and therefore formation of a valve body having a narrower channel groove.

摘要翻译： 通过压力将镁或镁合金的熔融液体浇注到使用铸模形成的中空部分中，形成用于自动变速器的变速操作的用于液压油的通道槽的阀体 。 在上述中，用于液压油的通道槽由于形成在模具上的凸起部分而形成，以便突出到中空部分中。 由于镁具有小的热容量，因此可以抑制在冷却和加热循环期间模具的温度变化。 此外，由于镁熔融液体对铸模没有反应性，所以凸部不劣化。 这允许使用其上形成有较薄凸起部分的模具，从而形成具有较窄通道槽的阀体。
