  • Hydraulic control apparatus
    Patent number: 9759314
    Abstract: A hydraulic control apparatus, wherein the first switching valve receives an input of one of the hydraulic pressure from the first electromagnetic valve device and the predetermined hydraulic pressure from the third switching valve, as a switching signal pressure, the first switching valve is switched from the first state to the second state in response to the input of the switching signal pressure, and the first switching valve is held in the second state, and the second switching valve receives an input of one of the hydraulic pressure from the first electromagnetic valve device and the predetermined hydraulic pressure from the third switching valve, as a holding pressure for holding the normal supply state.
