Patent ID: 8479903

Claim:
A hydraulic control device for a transmission, the hydraulic control device regulating hydraulic pressure of oil from an oil pressure source to generate line pressure, and selectively applying the generated line pressure to at least two kinds of controlled objects, the hydraulic control device comprising: linear solenoid valves each controlling hydraulic pressure in order to apply the line pressure to a corresponding switching valve in accordance with electromagnetic force of a solenoid of the corresponding linear solenoid valve; and wherein each switching each valve selectively switches at least the two kinds of controlled objects to apply the hydraulic pressure applied from the corresponding linear solenoid valve to the switched controlled object, wherein a feedback oil passage is provided for each of the switching valves, the feedback oil passage is branched from one of a plurality of output oil passages of the corresponding switching valve and the feedback oil passage is connected to a feedback port of the corresponding linear solenoid valve.
