摘要： PURPOSE:To lighten the shift shock by controlling the pressure in the back pressure chamber of an accumulator on the basis of the output of a sensor for detecting the revolution speed which varies in the selection of shift valves. CONSTITUTION:In case of up-shift in the first speed second speed, the revolution speed on the input side varies on the start of engagement of the second brake B2 by the selection of a shift valve 60, and said variation is detected by a sensor 45, and a control part C properly adjusts the control pressure by controlling a pressure adjusting valve S4 on the basis of the detection, and the hydraulic pressure which is properly adjusted through a control valve 72 is supplied into the back pressure chamber 71a of an accumulator 71. Therefore, the hydraulic pressure of the brake B2 smoothly varies, and also the output torque smoothly varies. In the selection of other shift valves 61 and 62, each hydraulic pressure in the back pressure chambers 69a and 70a of the accumulator is adjusted according to the revolution speed detected by the sensor 45. Thus, the shift shock can be lightened.

摘要： PROBLEM TO BE SOLVED: To reduce the size of an electromagnetic pump by suppressing leakage of working fluid pumped from an electric pump.SOLUTION: The hydrostatic pressure control device is provided with a switching valve 60 that selectively switches between: communication of an output port oil channel 33, which is connected to the output port 42c of a linear solenoid valve SLC1, with a clutch oil channel 34, which is connected to a clutch hydraulic chamber 80; and communication of a discharge port oil channel 36, which is connected to the discharge port 52b of an electromagnetic pump 50, with the clutch oil channel 34. An accumulator 70, which functions as a damper, is connected to the output port oil channel 33. Because the accumulator 70 is not connected to the path from the discharge port 52b of the electromagnetic pump 50 to the clutch hydraulic chamber 80 (discharge port oil channel 36, switching valve 60, clutch oil channel 34), leakage of working fluid during drive of the electromagnetic pump 50 can be suppressed. As a result, it is possible to design a smaller electromagnetic pump 50 by designing the transfer capacity of the electromagnetic pump 50 to be adequate for what is required.
