Description

【０００１】
【発明の属する技術分野】
この出願の発明は、車両のアンチロックブレーキ装置のブレーキ液圧制御弁等に使用する電磁弁に関し、特に、電気コイルへの通電・非通電により往復変位させて弁部材を開閉動作させるプランジャを収納させるスリーブの弁ハウジングへの固定装置に関するものである。
【０００２】
【従来の技術】
従来のこの種の電磁弁としては、特開平６−２４１３４２号公報に記載されたものが挙げられる。この電磁弁においては、一端を閉塞し他端を開口させたスリーブの他端にテーパ付きフランジ部を形成し、スリーブの他端を挿入する穴を弁ハウジングに形成し、この穴の奥部にはスリーブのテーパ付きフランジ部を受け止めさせるテーパ付き段部を形成したコアを受け止めさせる段部とコアのテーパ付き段部に受け止めさせたテーパ付きフランジ部との間に環状隙間を持って対向するアンダーカット部とを設け、環状スペーサを穴内に、その先端部が塑性変形して環状隙間に食い込むまで押し込むことによってスリーブを弁ハウジングに液密に固定するものである。
【０００３】
【発明が解決しようとする課題】
上記の電磁弁において、スリーブの内部には高い液圧が加わり、スリーブのテーパ付きフランジ部の復元曲げ応力以上の液圧が加わることでスリーブが抜けてしまう。
【０００４】
この出願の発明は、環状スペーサを用いてスリーブを固定する固定装置であって、スリーブのフランジ部のスリーブの復元曲げ応力を従来装置より向上させた固定装置を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的に従うこの出願の発明に係る電磁弁のプランジャ収納スリーブ固定装置は、一端が閉塞し他端が開口したスリーブの他端を弁ハウジングに液密に固定し、このスリーブの外周側に配置した電気コイルへの通電・非通電により往復変位させて弁部材を開閉動作させるプランジャを前記スリーブに収納させた電磁弁であって、前記スリーブの前記他端にフランジ部を形成し、前記スリーブの前記他端を挿入する穴を前記ハウジングに形成し、この穴の奥部には前記フランジ部を受け止めさせる段部とこの段部に受け止めさせた前記フランジ部との間に環状隙間を持って対向するアンダーカット部とを設け、環状スペーサを前記穴内に、その先端部が塑性変形して前記環状隙間に食い込むまで押し込むことによって前記スリーブを前記弁ハウジングに固定した電磁弁において、前記スリーブの前記フランジ部を該スリーブの外周面に対し略直角に形成すると共に、前記スリーブの前記フランジ部と前記環状スペーサとの間にテーパ付き外周面を持った略直角三角形状断面のサブ環状スペーサを介在させたものである。
【０００６】
かかる構成の固定装置においては、スリーブのフランジ部が該スリーブに外周面に対し略直角であることにより該フランジ部の復元曲げ応力が従来装置に比べて数段向上し、従って従来装置より高い液圧に耐えることができる。
【０００７】
【実施の形態】
以下、この出願に係る発明の電磁弁のプランジャ収納スリーブ固定装置の実施形態を図に基づき説明する。
【０００８】
図１は電磁弁の断面図であり、電磁弁１０の弁ハウジング１１には段付き穴１２と液圧通路１３，１４，１５が形成されている。穴１２内には、上端が閉塞し下端が開口しており且つ磁性体製のプランジャ１６を収納した非磁性体製のスリーブ１７と、このスリーブ１７の開口からスリーブ内に挿入された小径部とスリーブ１７の外に位置する大径部とを有した磁性体製のコア１８が挿入され固定装置１９により固定されている。
【０００９】
穴１２内にはコア１８により液圧室２０が区画され、この液圧室２０と液圧通路１３とを連通する通孔を中心に有した弁座部材２１が弁ハウジング１１に固定されている。コア１８を上下方向に摺動可能に貫通するロッド２２は、その上端部でプランジャ１６に結合され、またその下端には弁座部材の中心孔を開閉するための弁部材２３を形成されている。スリーブ１７内に配置されたスプリング２４はプランジャ１６およびロッド２３を上方に付勢し、弁部材２３を弁座部材２１から離間させて電磁弁１０を開状態とする。液圧通路１４，１５は液圧室２０と連通する。
【００１０】
弁ハウジング１１の外にて電気コイル２５がスリーブ１７の外周を取り巻くように配置され弁ハウジング１１に対して固定される。電気コイル２５が通電された場合、プランジャ１６を下方へ変位させる吸引力がプランジャ１６とコア１８との間に発生し、プランジャ１６およびロッド２２がスプリング２４の付勢力に抗して下方へ変位し、弁部材２３が弁座部材２１に接して弁座部材２１の中心孔を塞ぎ、電磁弁が閉状態となる。
【００１１】
図２は図１に示す固定装置１９の拡大図である。図１および図２に示すように、固定装置１９は、スリーブ１７の外周面に対し略直角のフランジ部２６をスリブ１７の下端に形成し、弁ハウジング１１の穴１２の奥部にはコア１８の大径部を下方から受け止めさせる段部２７を形成し、スリーブ１７のフランジ部２６をコア１８の大径部に下方から受け止めさせ、テーパ付き外周面を持った略直角三角形状断面のサブ環状スペーサ２８をスリーブ１７の外周に嵌めてフランジ部２６により下方から受け止めさせ、弁ハウジング１１にはサブ環状スペーサ２８の外周面と環状隙間を持って対向するアンダーカット部２９を形成し、楔状断面を持った環状スペーサ３０をスリーブ１７の外周に嵌めて穴１２内にその入り口から、環状スペーサ３０の先端部（下端部）が塑性変形して環状隙間に食い込むまで押し込むことで構成したものである。コア１８の大径部は穴１２に圧入してコア１８と穴１２の周壁との間を液密とし、環状スペーサ３０の押し込みによる荷重でフランジ部２６とコア１８との間を液密とする。サブ環状スペーサ２８は、環状スペーサ３０の先端部を塑性変形させるために必要な押し込み荷重を少なくするためのものである。
【００１２】
かかる固定装置１９においては、スリーブ１７のフランジ部２６がスリーブ１７の外周面に対し略直角であることによりフランジ部２６の復元曲げ応力が高く、スリーブ１７の内部に加わる液圧に対する抜け止め力が大きくなり、つまり耐圧性能が向上する。
【００１４】
なお、スリーブ１７のフランジ部２６を受け止めさせる段部は弁ハウジング１１に直接形成してもよい。
【００１５】
【発明の効果】
この出願の発明に係る電磁弁のプランジャ収納スリーブ固定装置は、スリーブのフランジ部をスリーブの外周面に対し略直角にしたことにより、フランジ部の復元応力が大きく、高い耐圧性能となる。

[0007]
Embodiment
Hereinafter, an embodiment of a plunger housing sleeve fixing device for an electromagnetic valve according to the present invention will be described with reference to the drawings.
[0008]
FIG. 1 is a sectional view of a solenoid valve, in which a valve housing 11 of a solenoid valve 10 is formed with a stepped hole 12 and hydraulic passages 13, 14, 15. In the hole 12, a sleeve 17 made of a non-magnetic material having a closed upper end and an open lower end and containing a plunger 16 made of a magnetic material, and a small-diameter portion inserted into the sleeve from the opening of the sleeve 17. A core 18 made of a magnetic material having a large diameter portion located outside the sleeve 17 is inserted and fixed by a fixing device 19.
[0009]
A hydraulic chamber 20 is defined in the hole 12 by a core 18, and a valve seat member 21 having a through hole communicating the hydraulic chamber 20 with the hydraulic passage 13 is fixed to the valve housing 11. . A rod 22 that penetrates the core 18 in a vertically slidable manner is connected to the plunger 16 at an upper end thereof, and has a valve member 23 formed at the lower end thereof for opening and closing a center hole of a valve seat member. . The spring 24 disposed in the sleeve 17 urges the plunger 16 and the rod 23 upward, and separates the valve member 23 from the valve seat member 21 to open the solenoid valve 10. The hydraulic passages 14 and 15 communicate with the hydraulic chamber 20.
[0010]
An electric coil 25 is arranged outside the valve housing 11 so as to surround the outer periphery of the sleeve 17 and is fixed to the valve housing 11. When the electric coil 25 is energized, a suction force for displacing the plunger 16 downward is generated between the plunger 16 and the core 18, and the plunger 16 and the rod 22 are displaced downward against the urging force of the spring 24. Then, the valve member 23 comes into contact with the valve seat member 21 to close the center hole of the valve seat member 21, and the solenoid valve is closed.
[0011]
FIG. 2 is an enlarged view of the fixing device 19 shown in FIG. As shown in FIGS. 1 and 2, the fixing device 19 has a flange portion 26 formed at a lower end of the slab 17 at a substantially right angle to the outer peripheral surface of the sleeve 17, and a core 18 at the back of the hole 12 of the valve housing 11. A step 27 for receiving the large diameter portion from below is formed, the flange portion 26 of the sleeve 17 is received by the large diameter portion of the core 18 from below, and a sub-circular triangular cross section having a tapered outer peripheral surface is provided. The spacer 28 is fitted on the outer periphery of the sleeve 17 and received from below by the flange portion 26. An undercut portion 29 is formed in the valve housing 11 to face the outer peripheral surface of the sub-annular spacer 28 with an annular gap. The annular spacer 30 is fitted around the outer periphery of the sleeve 17 and the front end (lower end) of the annular spacer 30 is plastically deformed from the entrance into the hole 12 so that the annular gap 30 is eaten. Which is constituted by pushing up writing. The large-diameter portion of the core 18 is press-fitted into the hole 12 to make the space between the core 18 and the peripheral wall of the hole 12 liquid-tight, and the load between the annular spacer 30 and the flange portion 26 and the core 18 to be liquid-tight. . The sub-annular spacer 28 is for reducing the pushing load required for plastically deforming the distal end of the annular spacer 30.
[0012]
In the fixing device 19, since the flange portion 26 of the sleeve 17 is substantially perpendicular to the outer peripheral surface of the sleeve 17, the restoring bending stress of the flange portion 26 is high, and the retaining force against the hydraulic pressure applied to the inside of the sleeve 17 is reduced. In other words, the breakdown voltage performance is improved.
[0014]
The step for receiving the flange 26 of the sleeve 17 may be formed directly on the valve housing 11.
[0015]
【The invention's effect】
