PURPOSE: An accumulator is provided to reduce time for releasing pressure and to improve transmission stability and transmission quality. CONSTITUTION: An accumulator comprises a valve block(10), an accumulator chamber(12), a pressing path(13), a releasing chamber(14), a releasing path(15), a discharging path(16), and an accumulator valve(20). The valve block comprises a main path(11) for connecting a hydraulic line between an actuator and a transfer valve. The accumulator chamber is adjacent to the main path. The pressing path connects the main path to one side of the accumulator chamber. The releasing chamber is adjacent to the accumulator chamber. The releasing path is connected to the releasing chamber while passing through the middle part of the accumulator chamber from the main path. The discharging path is connected to an oil tank while passing through the other spot of the accumulator chamber from the releasing chamber. The accumulator valve is installed in the accumulator chamber in a state where a return spring(23) is supported in the opposite side of the pressing path to receive hydraulic pressure from the pressing path. |
