摘要： In a hydraulic control device, when a solenoid pressure from a linear solenoid valve is not supplied to a brake, which is normally not engaged at the same time as a brake, not to engage the brake, a switching valve is supplied with a line pressure as a signal pressure for establishing a blocked/discharge state in which supply of the solenoid pressure to the brake is blocked and a hydraulic pressure can be discharged from the brake. When the solenoid pressure is supplied to the brake to engage the brake, the switching valve is supplied with a modulator pressure, which is lower than the line pressure, as a signal pressure for establishing a communicated state in which the solenoid pressure can be supplied to the brake.

摘要： A C1 switching valve 80 establishes a first supply state, in which a C1 solenoid pressure Pslc1 can be supplied to a clutch C1, when a line pressure PL is supplied as a holding pressure, and when a modulator pressure Pmod is supplied as a holding pressure and a B1 solenoid pressure Pslb1 is not supplied. The C1 switching valve 80 establishes a second supply state, in which the line pressure PL can be supplied to the clutch C1, when the modulator pressure Pmod is supplied as a holding pressure and the B1 solenoid pressure Pslb1 is supplied. The C1 switching valve 80 is supplied with the modulator pressure Pmod as a holding pressure when an abnormality occurs in supply of the C1 solenoid pressure Pslc1.

摘要： An oil pressure control apparatus for an automatic transmission configured with an oil pressure servo that engages and disengages a friction engagement element. The friction element is engaged by first and second hydraulic oil chambers that individually provide low torque, and can provide a higher torque when working in combination. A failure solenoid valve outputs a signal when a failure occurs to stop oil pressure to an oil pressure servo. Valves are configured to determine whether oil pressure is supplied to or discharged from the first and second hydraulic oil chambers. A switching valve is switched on the basis of the failure signal, and an oil pressure can be individually supplied to and discharged from the first and second hydraulic oil chambers based on the status of the switching solenoid valve and the signal from the failure solenoid valve.

摘要： A piston is slidably provided in a cylinder and partitions a first pump chamber, and a second pump chamber connected to an object to be operated. A first on-off valve is provided between the first pump chamber and the outside. A second on-off valve is provided in a connecting flow passage that connects the first pump chamber and the second pump chamber to each other. When the piston is moved forward by an electromagnetic force of a solenoid portion, a capacity of the first pump chamber decreases, and a capacity of the second pump chamber increases. When the piston is moved backward by a biasing force of a spring, the capacity of the first pump chamber increases, and the capacity of the second pump chamber decreases. A pressure receiving area of the front face of the piston is larger than that of the back face thereof.
