この永久磁石の上に中ヨーク12.12が截せられる。The second figure shows an exploded perspective view of the polarized solenoid of the present invention. In the figure, reference numeral 11 denotes a U-shaped first yoke, and connecting recesses provided at the ends of the middle yoke 12 and 12 near both ends. Protrusions 1 for fitting with the locations 12a and 12a'
1a is formed. 1-3 is a plastic coil frame, which has a hole 15 in the center through which the plunger 14 is inserted, and a collar 16.1 in the side wall.
7.18 is provided, a coil 19 is wound between the collar portions 16.17, and a plate-shaped permanent magnet 20.20 is attached to the recess VC between the collar portions 17.18. Further, a middle yoke 12.12 is cut out on this permanent magnet.

反対方向に流れている。従って空FAAでは磁束が増大
し、吸引力が大きくなり、2F?iBでは磁束が減少し
、吸引力は小さくなる。Figure 5 shows the flow of magnetic flux. The solid line shows the magnetic flux caused by the permanent magnet, and the broken line shows the magnetic flux caused by the coil. In the state shown in the figure, the magnetic flux of the permanent magnet and the coil magnetic flux are superimposed in the air gap A, and flow in opposite directions in the air gap B. Therefore, in the empty FAA, the magnetic flux increases, the attractive force increases, and 2F? At iB, the magnetic flux decreases and the attractive force becomes smaller.
故にプランジャ14はを11JA側に吸引されることに
なる。Therefore, the plunger 14 is attracted to the 11JA side.
コイル励磁を図と逆にするとプランジャは空隙B側に吸
引される。If the coil excitation is reversed from the diagram, the plunger will be attracted to the air gap B side.
