Description
【考案の詳細な説明】 （産業上の利用分野） 本考案はスプール弁に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a spool valve.
（従来の技術） スプール弁は通常、例えば日産自動車（株）発行「RN4F
02A型、RL4F02A型オートマチックトランスアクスル整備
要領書」（A261C06）に記載の自動変速機に用いられて
いる如く、バルブボデーの孔内にスプールを摺動自在に
挿置して構成し、各種油圧の切換えや、各種油圧の調整
に実用する。(Prior art) Spool valves are usually, for example, "RN4F" issued by Nissan Motor Co., Ltd.
02A, RL4F02A automatic transaxle maintenance manual ”(A261C06), the spool is slidably inserted in the hole of the valve body and used for automatic transmission. Practical for switching and adjusting various hydraulic pressures.
（考案が解決しようとする課題） ところで、スプールのランド幅やランド間間隔、更にラ

は、図示位置からは大径のランド1cが孔2cに嵌合して芯
出しに寄与するのみであるため、小径のランド1a,1bを
対応する孔2a,2bに対し芯出し状態に保つ保障がない。FIG. 3 shows the spool 1 in the state of being inserted into the valve body 2, and the lands 1a, 1b, 1c of the spool 1 are shown.
The positions in which the respective holes are fitted into the holes 2a, 2b, 2c of the valve body 2 are the fully inserted state of the spool 1. The land 1c of the spool 1 protrudes from the valve body 2 until just before the state shown in the drawing is being inserted, and the protruding end can be held with a finger to perform spool insertion work. Can not be held with fingers. Therefore spool 1
Since the large-diameter land 1c only fits into the hole 2c from the position shown and contributes to the centering, it is guaranteed that the small-diameter lands 1a and 1b are centered with respect to the corresponding holes 2a and 2b. There is no.
これがためスプール１を図示位置より押込む時、ランド
1a,1bが孔2a,2bに対し干渉するのを避けられず、スプー
ルの組立作業性が悪くなったり、上記の干渉で傷が生じ
て歩留りの悪化を招く。Therefore, when pushing the spool 1 from the position shown in the figure, the land
It is unavoidable that the holes 1a and 1b interfere with the holes 2a and 2b, the workability of assembling the spool is deteriorated, and the above-mentioned interference causes scratches to deteriorate the yield.
この問題解決のためにはランド1c及び孔2cの全長を長く
して両者間のクリアランスにともなうスプール１のこじ
れが少なくなるようにすることが考えられるが、この場
合弁の大型化を招き実用的でない。In order to solve this problem, it is conceivable to increase the total length of the land 1c and the hole 2c to reduce the twisting of the spool 1 due to the clearance between them, but in this case, the valve becomes large and it is practical. Not.
本考案はこの問題を解決するようスプールを改良するこ

ち来し得るようにしたことを特徴とするものである。(Means for Solving the Problems) For this purpose, the present invention comprises a spool slidably inserted in a hole formed in a valve body, and the spool has a diameter that gradually increases from the front end in the insertion direction. After having a plurality of lands and the rear end surface in the insertion direction of the spool has passed through the opening edge of the hole, a plurality of lands among the lands are
In a spool valve that starts to fit into the corresponding hole diameter portion of the hole, a jig hole is formed in the rear end surface of the spool in the insertion direction, and a plurality of spools are formed by using a spool centering jig that is inserted into the hole. The land can be brought into a centered state fitted in the corresponding hole diameter portion.
（作用） スプールはバルブボデーの孔内で摺動して所定の機能を
果たす。(Operation) The spool slides in the hole of the valve body to perform a predetermined function.

されるよう手で位置合せしながらスプールを押込む。By the way, when inserting the spool into the hole of the valve body, a spool centering jig is installed in the jig hole provided on the rear end face of the spool in the insertion direction when the spool cannot be held by hand during this insertion work. Make it penetrate and hold the spool in your hand through this jig. Then, the spool is pushed through the jig while manually aligning the plurality of lands so that a plurality of lands are fitted in the corresponding hole diameter portions of the valve body and centered.

こともない。Therefore, even after the spool cannot be held by hand, the spool can be reliably inserted into the corresponding hole while being centered, and even with the spool valve of the above type, it is possible to prevent deterioration of assembly workability and yield. it can. Further, since this function and effect are achieved without lengthening the land and the hole diameter portion corresponding thereto in the axial direction, the valve does not become large.
（実施例） 以下、本考案の実施例を図面に基づき詳細に説明する。Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

6,7を塞ぐ。FIG. 1 is an embodiment in which the spool valve of the present invention is constructed as a 3-4 shift valve of an automatic transmission. The 3-4 shift valve includes spools 3 to 5 in addition to the spool 1 described in FIG. , Butt them against each other and tandemly insert them into the valve body 2 and plug both ends of the valve body into plugs.
Block 6,7.

スプール１を押込む。In this example, a drill hole 8 is formed in the rear end face of the spool 1 in the insertion direction which causes the above problem, and this is formed as a jig hole. To explain the method of inserting the spool 1 using the hole 8, the spool centering jig 9 is inserted into the hole 8 immediately before the insertion position shown in FIG. 2 where the spool 1 cannot be held directly by hand. Then, the spool 1 is held by hand through the jig 9 and inserted into the illustrated position. Here, the spool 1 via the jig 9
While twisting in the direction perpendicular to the axis, the spool lands 1a, 1b are adjusted in position so as to be centered in the corresponding holes 2a, 2b, and the spool 1 is pushed in in this state.

It is possible to prevent the assembly workability and the yield from being deteriorated due to the interference between the two.

ない。(Effect of the Invention) As described above, since the spool valve of the present invention has the jig hole on the rear end face in the insertion direction of the spool as described above, the jig hole can be held even after the spool cannot be held in the hand during the process of entering. It is possible to insert the spool centering jig into the, and surely advance the insertion while centering the spool therethrough, and due to the land diameter being successively smaller in the spool inserting direction,
Even if the spool valve, in which a plurality of lands start to fit into the corresponding hole diameter portion only after the rear end surface of the spool in the insertion direction passes through the opening edge of the spool insertion hole, deterioration of assembly workability and yield is prevented. obtain. Further, since this effect is achieved without increasing the axial length of the land and the corresponding hole diameter portion, the valve does not become large.
