Abstract
A hydraulic controller for a hydraulic actuator () incorporated in a power transmission mechanism, wherein an accumulator () is connected to an oil supply passage () for the hydraulic actuator () for supplying oil from a pump () via a regulator () and a one-way valve () and a lubricating oil passage () for the power transmission mechanism is connected to the regulatorin the drain side thereof, by which energy consumption can be reduced maximally even if the pump () is regularly driven for lubrication. It is provided with a hydraulic pressure switching means () capable of freely switching a setting pressure of the regulator () between a high pressure and a low pressure. While the hydraulic pressure of the oil supply passage () is higher than or equal to a pressure at which the hydraulic actuator () can be operated, the controller maintains the setting pressure of the regulator () at the low pressure to reduce a work load of the pump
