油圧制御装置。 An accumulator is connected in the middle of a hydraulic oil supply and discharge path that supplies and discharges hydraulic pressure to a hydraulically operated friction engagement device for speed change control, and oil that communicates and connects the hydraulic oil supply and discharge path to an accumulator chamber of the accumulator. In a hydraulic control device for an automatic transmission in which a one-way valve and a throttle element are provided in parallel to each other in a passageway to allow oil to flow only toward the accumulator chamber, the throttle element has a throttle flow path that is smaller than the diameter of the throttle hole. A hydraulic control device comprising a long viscous highly sensitive restricting element.
