VIBRATION-SUPPRESSING CONTROL CIRCUIT
In a vibration suppression control OFF state, a signal pressure supply control valve stops supplying a first signal pressure, a pressure-regulating valve is positioned in a first position in which a supply/discharge port is connected to a pump port, and an open/close signal pressure is not supplied to an open/close control valve, such that an open/close valve is closed. When the vibration suppression control OFF state switches to a vibration suppression control ON state, the signal pressure supply control valve allows supplying the first signal pressure, and the pressure-regulating valve is brought into a second position in which the supply/discharge port is connected to a tank port, such that a pressure of a pressure accumulator decreases. In the vibration suppression control ON state, when the pressure of the pressure accumulator has become equal to a pressure of a pressure chamber, the pressure-regulating valve is brought into a third position in which the supply/discharge port is blocked, and the open/close signal pressure is supplied to the open/close control valve, such that the open/close valve is opened.
