し戻すばねである。Figures 2 and 3 are cross-sectional views showing the structure of a conventionally used solenoid valve. The coil 1 is formed of an insulating material and wound around nine bobbins 2, and the center hole and the surrounding area of the bobbin 2 are surrounded by a core 3 made of a magnetic material.
and case 4. A plunger 5 is movably housed opposite the core 3 fitted into the center hole of the bobbin 2, and when the coil 1 is energized, the plunger 5
The bushing rod 6t fixed to the granger 5 can be moved to clean the work. The nine wires 7 marked with arrows are the main magnetic flux passages, and the coil spring 9 housed in the recess at the center of the core 3 is a spring that pushes back the plunger 5.

いた。Since such a solenoid valve is attached to the engine case 8, which heats up to a maximum of 150° C., the temperature of the solenoid valve tends to rise. Further, since the coils 1 are assembled into 11 pieces and are fixed together, the surface area of the coils 1 is small, and its internal temperature tends to rise. Therefore, coil IK large excitation electric current IL
It was impossible to do so, resulting in a solenoid valve with low efficiency.

。The purpose of the present invention is to improve the drawbacks of the prior art and provide a J-type solenoid valve that exhibits a small temperature rise even when a large excitation current is applied. A coil and a magnetic plate were wound around the outer periphery in a superimposed manner so that the outer periphery surrounded the inner periphery, and the above coils were connected in series, and the coils in contact with each other were constructed by winding conducting wires in opposite directions. Torororu.

している。FIG. 2 is a sectional view of a solenoid valve according to an embodiment of the present invention, and the same parts as in FIG. 1 are given the same reference numerals. A coil spring 9 is housed in a recess at the center of the core 3, which is made of magnetic material, and its left end is in contact with the shaft mK of the disc-shaped grunge 5. The outside of the core 3 is surrounded by an iron plate 1011, and a coil 1a is thinly wound around the outside of the core 3 with insulating paper interposed therebetween.

The outside of the coil 1a is surrounded by an iron plate 10b with an insulating paper in between, and the outside *'i coil 1b is wound thinly, but the winding direction of the coil 1a and the winding direction of the coil 1b are opposite. direction. That is, when the coil 1b is wound from the front side of the page toward the back side g4, the coil 1b is wound at the same location so as to come out from the back side of the page to the front side.

It is tightly attached to the inside of the right end plate. Note that the left end of each iron plate 10 faces the right side surface of the plunger 5 with a gap interposed therebetween.

る。FIG. 3 is an enlarged sectional view of the main part of the solenoid valve shown in FIG. 2, and the broken arrow line indicates the magnetic flux passage 7'. Coil 1a and coil as above! Since the winding directions of the coils 1j to 1e are opposite to each other, when the coils 1j to 1e are energized, the nine magnetic fluxes passing to the left of the iron plate 10b'ft are shunted left and right by the plunger 5 and return through the iron plate 10a and IOC. When this happens, the granger 5 compresses the coil spring 9 and is attracted in the direction of the coil 1.゛Coil 1a~
The Joule heat generated in the winding 1.
The heat is transmitted to the iron plates 1 (1 to 1), and is transmitted to the case 4 and radiated into the outside air. Since the contact area between the coils 1a to IC and the iron plates 10J to 1 (l) is large, Heat transfer between the coil 1 and the iron plate 10 is good.
また、鉄板1の熱伝導係数が大きいので伝熱が良好であ
る。したがって、ケース4内のコイル部内の温度分布は
均一となり、従来のようにコイル1の内部が高温状層と
なるようなことはない。Furthermore, since the iron plate 1 has a large thermal conductivity coefficient, heat transfer is good. Therefore, the temperature distribution inside the coil section in the case 4 becomes uniform, and the inside of the coil 1 does not become a high temperature layer unlike the conventional case.
一般に自動車用自動変速機の温度上昇は150’C根度
であり、コイル巻線の絶縁材料の耐熱m度は200Cが
限界とされている。このため、ソレノイドバルブの許容
温度上昇F1.50 C1111である。Generally, the temperature rise of an automatic transmission for an automobile is 150 degrees Celsius, and the heat resistance of the insulating material of the coil winding is said to be limited to 200 degrees Celsius. Therefore, the allowable temperature rise of the solenoid valve is F1.50 C1111.

イル10巻線の抵抗損失による温度上昇は500以下G
′こしたいが、本実施例のコイル1によって始めて可能
となった。When applying a DC excitation current to the solenoid valve, heat generation due to iron loss is considered to be negligible, so the temperature rise due to resistance loss in the 10th coil winding is less than 500G.
'I wanted to do this, but it became possible for the first time with the coil 1 of this embodiment.

に吸引力に変換させることが可能となった。Furthermore, since a plurality of iron plates 10i are provided, the total amount of magnetic flux can be distributed to these iron plates 10, thereby reducing the amount of magnetic flux passing through one iron plate 10, thereby reducing the magnetic flux density. As a result, it has become possible to use the iron plate 101 with high magnetic permeability, and it has become possible to effectively convert the electric energy applied to the coil 1 into attractive force.

は増加しない。In the case of FIG. 2, the coil IK is energized and the granger 5 is attracted by the coil IK, but at this time the bushing rod 6 fixed to the granger 5 is pulled back. In addition, the right end of the nine-segment rod 14 is constantly in contact with the tip of the bushing rod 6, which is pressed by human pressure.
In this state, the input pressure from the input pressure passage 11 is communicated with the output pressure passage 12 and the drain passage 13, so the output pressure does not increase.

The bushing rod 6 is pushed out by the force of the coil spring 9,
Push the spool 14 to the left to close the drain boat 15ai. Therefore, the input pressure flows through the passage in the spool 14 to the output pressure passage 12, increasing the pressure in the closed container connected to the output pressure passage 12 and operating the automatic transmission.

で兼期間好適に作動するという効果をもっている。In the solenoid valve of this embodiment, the central core is wound and a plurality of layers of coils and iron plates are superimposed, and the coils that are in contact with W4 are wound in the opposite direction, so that the required amount of magnetic flux is distributed over multiple iron plates. The amount of magnetic flux of a single sheet weight is reduced by distributing the magnetic flux to the magnetic flux density. Therefore, the iron plate can be used with a high permeability, and the 9' wax energy applied to the coil can be efficiently converted into suction force, and the temperature rise in the coil part is reduced, so it is possible to It has the effect of operating suitably for a long period of time.
