    摘要： A hydraulic control system comprises: a regulator valve, which regulates a fluid pressure established by an oil pump to an operating pressure required in a control circuit; a signal pressure establishing valve, which applies a signal pressure to the regulator valve to determine a level of the fluid pressure to be established by the regulator valve; and an accumulator, which accumulates the operating pressure to be applied to the control circuit. The hydraulic control system is characterized by: an accumulator control valve, which is arranged between the accumulator and the control circuit, and which is adapted to connect the accumulator with the control circuit when opened, and to disconnect the accumulator from the control circuit when closed; and a signal pressure feeding passage, which delivers the signal pressure established by the signal pressure establishing valve to a signal pressure port of the accumulator control valve thereby actuating the accumulator control valve in accordance with the signal pressure.

    摘要： A hydraulic control unit is provided. A valve is comprised of a piston having a valve element, a cylinder holding the piston while allowing to reciprocate axially, a positive pressure chamber formed on one side of the piston to which pressure to open the valve is applied, a back pressure chamber formed on the other side of the piston to which the pressure to close the valve is applied, and a connection passage for differentiating pressures in the positive pressure chamber and the back pressure chamber. A pilot valve selectively connects the back pressure chamber with a site where the pressure is lower than that of the back pressure chamber. Hydraulic pressure lower than that applied to positive pressure chamber is applied to a low pressure section. The hydraulic control unit comprises a means to deliver the fluid from the low pressure section to the back pressure chamber if an opening motion of the valve is slower than a predetermined reference value, by opening the pilot valve to connect the back pressure chamber with the low pressure section.
