Claims

[Claims for Utility Model Registration] A case made of a magnetic material, a solenoid coil housed in the case, a bobbin around which the coil is wound, and a bobbin attached to one end of the case and protruding into the center of the bobbin from one end. a fixed iron core having a section, a magnetic path plate of a magnetic material provided at the other end of the bobbin, and a magnetic path plate movable in the axial direction at the other end of the bobbin in the magnetic path between the magnetic path plate and the fixed iron core; a magnetic plunger which is provided in the coil and is attracted toward the fixed iron core by energizing the coil; and a spring which presses the plunger in a direction opposite to the fixed iron core, and the magnetic path plate is The case is divided into two chambers, in one of which a coil and spring for driving the plunger are arranged, and in the other chamber there is a valve that is opened and closed by the plunger and a ball that is operated by a small diameter part protruding from the tip of the plunger. The valve chamber has an input hole, a discharge port, and an output port at an intermediate position between the input hole and the discharge port, and the check valve faces the input hole. When the valve that is opened and closed by the plunger is closed, the flow from the input hole to the discharge hole is blocked, and at the same time, the check valve is opened to allow flow from the input hole to the output port. On the other hand, when the valve opened and closed by the plunger is opened, the check valve closes and a flow is generated from the output port to the discharge hole. so as not to escape from the chamber and not obstruct fluid flow from the output port to the input hole;
A solenoid valve, characterized in that it is formed in an input hole plate separate from the case.
