。[Claims for Utility Model Registration] A cylinder provided in a magnetic circuit generated by an electromagnetic coil, a high-pressure side port and a low-pressure side port each opening at one end of the cylinder, and the above-mentioned cylinder formed of a magnetic material. It has a plunger that is slidably inserted into the cylinder, and biasing means that biases the plunger from the other end of the cylinder to the one end. When the electromagnetic coil is energized, the plunger is moved by the electromagnetic force. When the plunger moves to the other end within the cylinder against the urging force of the urging means, the two ports communicate through the cylinder, and the current to the electromagnetic coil is cut off, the plunger moves to the other end side of the cylinder against the urging force of the urging means. In the electromagnetic valve, the plunger is moved to the one end side in the cylinder by the urging force of the solenoid valve, so that the space between the two ports is closed. It is divided into a plunger and a second plunger on the other end side which is energized by the energizing means, and a through hole passing through the first plunger in the axial direction communicates with the low pressure side port. A pilot-type solenoid valve characterized by having the following features:
