The regulating valve has: a valve seat formed between the intermediate-pressure chamber and the low-pressure chamber; a valve body that comes into contact with the valve seat from the low-pressure chamber side; a spring presser that moves inside the valve chamber due to the pressure difference between the pressure of the low-pressure chamber and the pressure of the high-pressure chamber; and a first coil spring that is provided between the valve body and the spring presser and that biases the valve body toward the valve seat and biases the spring presser toward the other end.
