  • Hydraulic controller
    Patent number: 9217446
    Abstract: A hydraulic controller includes: an accumulator connected to a main oil passage; a pressure storage use oil passage which branches off from the main oil passage and leads to the accumulator; an inlet port; a priority port; and a bypass port. The hydraulic controller includes a priority valve configured such that, at the time of storing pressure in the accumulator, of pressure oil that flows into the inlet port, the pressure oil at a flow rate for storing of pressure in the accumulator, which is a preset flow rate, flows out of the priority port, and the pressure oil at a surplus flow rate, which is a flow rate obtained by subtracting the flow rate for storing of pressure from the flow rate of the pressure oil flowing into the input port, flows out of the bypass port.
