<p>PURPOSE:To make a hydraulic circuit in a compact size by providing a function to switch two output oil pressures and a function to regulate the pressure of the both output oil pressures, and composing the hydraulic circuit with a single valve. CONSTITUTION:When the first electromagnetic valve 13 is in an operational condition and the second electromagnetic valve 14 is in an inoperational condition, the load of the first signal oil pressure P1 and the load of the first output oil pressure P4 are regulated to be balanced pressures. On the other hand, when the first electromagnetic valve 13 is in an inoperational condition and the second electromagnetic valve 14 is in an operational condition, the load of the second signal oil pressure P6 and the load of the second output oil pressure P3 are regulated to be balanced pressures. In such a way, a signal pressure regulating switch valve has a function to feed the oil pressure selectively to two clutches C1 and C2, and a function to regulatethe oil pressures to the clutches C1 and C2. As a result, a double-clutching can be prevented, and since only one valve is used, the hydraulic circuit can be made compact.</p> |
