用アクチュエータ。A cut valve that can shut off a passage connecting a mask cylinder and a brake cylinder; a pressure chamber provided between the cut bar and the brake cylinder; and a pressure chamber that opens and closes the cut valve and changes the volume of the pressure chamber. a servo piston that divides the inside of the housing into a variable pressure chamber and a low pressure chamber, and that moves according to the pressure difference between the two chambers to drive the hydraulic plunger;
A main spring provided in the low pressure chamber biases a hydraulic plunger in a direction in which the cut valve opens, and a valve device that connects the variable pressure chamber to a low pressure source and a high pressure source in a switchable manner,
The valve device includes a solenoid that is energized or demagnetized by a command from a control unit, and a solenoid that, when the solenoid is demagnetized, sits on a first valve seat to cut off communication between the variable pressure chamber and the high pressure source. , when the solenoid is energized,
a valve member seated on a second valve seat provided opposite to the first valve seat to cut off communication between the variable pressure chamber and the low pressure source; an actuator for an anti-skid device comprising: a first valve spring that biases the valve spring toward the valve spring; and a first valve spring that biases the valve member over its entire travel range; and a second valve spring that biases the valve member only when the valve member moves toward the second valve seat.
