回路に含まれるように構成した ことを特徴とするパイロツト型電磁弁。[Claims for Utility Model Registration] A cylinder provided in a magnetic circuit generated by an electromagnetic coil and having a high-pressure side port and a low-pressure side port opened at one end; a first plunger slidably inserted into one end of the cylinder; a through hole bored in the first plunger so as to communicate the low pressure side port with the back side of the first plunger; , a second member made of a magnetic material that is slidably inserted into the cylinder and pressed against the first plunger by the biasing means so as to close the through hole;
a plunger, when the electromagnetic coil is energized, the electromagnetic force causes the second plunger to move within the cylinder against the urging force of the urging means, opening the through hole;
A pilot type solenoid in which the back side of the first plunger communicates with the low-pressure side port and becomes low pressure, so that the first plunger moves into the cylinder and the two ports communicate with each other through the cylinder. In the valve, the first plunger and the second plunger are formed to face each other in a tapered shape, and at least the vicinity of the tapered part of the first plunger is formed of a magnetic material to control the magnetism of the electromagnetic coil. A pilot type solenoid valve characterized by being configured to be included in a circuit.
