    • 【課題】ハウジング内で軸方向に摺動自在に支持されるロッドの変位によって流路を開閉するバルブ装置において、ロッドに作用する横力を低減する。【解決手段】減圧弁1は、第1軸受18Aよりも先端側のロッド12の先端部12aが筒状部材40によって覆われている。筒状部材40は、第1ポート16から第2ポート17へ燃料が流れることによって生じるバルブ室15内の流れからロッドの先端部を保護する保護壁の役割を果たす。この筒状部材40の存在によって、バルブ室15内に形成される流れが直接ロッド12に衝突しにくくなる。すなわち、筒状部材40でロッド12を覆うことによって、バルブ室内の流れに晒されるロッド12の側面積を小さくすることが可能となり、結果として、ロッド12に作用する横力を低減することができる。【選択図】図2
    • 要解决的问题:减小作用在杆上的横向力,在用于通过将杆轴向滑动地支撑在壳体中的位置来打开和关闭流动通道的阀装置中。解决方案:减压阀1被圆柱形构件40覆盖 在相对于第一轴承18A的尖端侧的杆12的尖端部分12a处。 圆柱形构件40用作保护壁,用于保护杆的末端部分不受来自通过燃料从第一端口16流动到第二端口17而产生的阀室15中的流动。通过存在圆柱形构件40 在阀室15中形成的流体直接与杆12几乎碰撞。 也就是说,通过用圆柱形构件40覆盖杆12,可以减小暴露于阀室中的流动的杆12的侧面区域,结果,可以减小作用在杆12上的横向力。

    • PROBLEM TO BE SOLVED: To improve valve closing responsiveness in current-carrying OFF time to a coil, in a normally closed solenoid valve.SOLUTION: This solenoid valve applied as a suction valve part 30A of a high-pressure pump, generates electromagnetic attraction force between a flange 55A and a movable core 53 when carrying an electric current to the coil 51, and the movable core 53 moves in the attraction direction (the left direction of a drawing). When current-carrying to the coil 51 is turned off, the electromagnetic attraction force disappears, and the movable core 53 and a stem 41 integrally move in the anti-attraction direction (the right direction of the drawing) by energizing force of a second spring 43A. A valve element 32 also moves in the valve closing direction for seating on a seat part 316 of a seat member 31 by energizing force of a first spring 33. Since the energizing direction of the first spring 33 and the second spring 43A is the same, weight of the movable core 53 and the stem 41 does not become a load to valve closing operation of the valve element 32. The lightweight valve element 32 can move independently.

    • PROBLEM TO BE SOLVED: To improve responsiveness while preventing erosion caused by cavitation in a solenoid valve for opening and closing a liquid passage.SOLUTION: An armature chamber 17 receives an armature 18 and includes a first armature chamber 170 which is placed adjacent to one end surface of the armature 18 and communicates with a spring chamber 19, and a second armature chamber 171 which is placed adjacent to the other end surface of the armature 18. The armature 18 includes a primary communication passage 180 that makes the first armature chamber 170 communicate with the second armature chamber 171. An opening end on the primary armature chamber 170 side in the primary communication passage 180 is located at a position opposite to the spring chamber 19. Thus, when conduction to a coil is stopped, fuel flows into the spring chamber 19 without via a gap between the armature 18 and a stator core 10, the fuel smoothly flows in the spring chamber 19, and any cavitation hardly occurs.
    • 要解决的问题:提高响应性,同时防止用于打开和关闭液体通道的电磁阀中的气穴引起的侵蚀。解决方案:衔铁室17接收电枢18,并且包括第一衔铁室170,其邻近一端 电枢18的表面并与弹簧室19连通,第二衔铁室171邻近电枢18的另一个端面放置。电枢18包括主连通通道180,使第一衔铁室170连通 与第二电枢室171连通。主连通通道180中的主电枢室170侧的开口端位于与弹簧室19相对的位置。因此,当线圈的导通停止时,燃料流入弹簧 腔室19不经由电枢18和定子芯10之间的间隙,燃料在弹簧室19中平稳地流动,并且任何气蚀几乎不会发生 rs。

    • PROBLEM TO BE SOLVED: To provide a normally open type electromagnetic valve capable of reducing spring load when starting energization and increasing the spring load in an operational area with large magnetic attraction force while avoiding reduction in a magnetic pole surface.SOLUTION: Two springs 36, 38 are arranged in series and a spring receiving member 34 is arranged between the two springs 36, 38. In an operational area where magnetic attraction force is low and a position of a valve body 20 is closer to the fully opened position side than an intermediate position, the spring receiving member 34 is not abutted on a sleeve 12 or an armature 22 and both deflections of the two springs 36, 38 are changed, so that a synthetic spring constant is reduced. In an operational area where the magnetic attraction force is large and the position of the valve body 20 is closer to the fully closed position side than the intermediate position, the spring receiving member 34 is abutted on the sleeve 12 and the deflection of one spring 36 is not changed, so that the spring constant is increased.

    • PROBLEM TO BE SOLVED: To adjust an air gap in an axial direction formed between a stator core and an armature core without using any spacer, and without making work complicated in a solenoid valve.SOLUTION: A method for manufacturing a solenoid valve 1 includes a grinding step of grinding at least any one of a stator unit 41 and an armature unit 42. The grinding step is executed when precision of an air gap G1 in the axial direction is to be enhanced, and the precision of the air gap G1 in the axial direction is enhanced by the grinding without using any spacer. That is, according to the grinding, by setting the feed per revolution of a grinding wheel, and feeding the grinding wheel, the grinding for the portion of the set feed per revolution can be achieved with very high precision. Thus, the air gap G1 in the axial direction can be adjusted with high precision by using the grinding without using any spacer, and without making any work complicated.

    • PROBLEM TO BE SOLVED: To reduce necessary magnetic attractive force while suppressing vibration of a valving element.SOLUTION: In a high lift region, a fluid force applied to a valving element 20 is remarkably reduced and a variation amount of a fluid force versus a variation amount of lift of the valving element 20 is also reduced. Therefore, it is found that in the high lift region, the valving element 20 is largely and rapidly displaced by a slight variation of the magnetic attractive force applied to the valving element 20 and vibration of the valving element 20 is generated by the displacement to be a trigger. Consequently, a passage area between the valving element 20 located on a position most separated from a valve seat 181 and the valve seat 181 is set to a passage area of an orifice 180 or less. Thereby, only a lift region where a variation amount of a fluid force versus a lift variation amount is large, out of lift regions of the valving element 20, is used, so that a large displacement of the valving element 20 due to a slight variation of the magnetic attractive force can be avoided and vibration of the valving element 20 can be suppressed.
    • 要解决的问题:在抑制阀元件的振动的同时减少必要的磁吸引力。解决方案:在高提升区域中,施加到阀元件20的流体力显着减小,并且流体力相对于变化的变化量 阀元件20的升程量也减小。 因此,发现在高升程区域中,通过施加到阀元件20的磁吸引力的微小变化,阀元件20大幅度地迅速地移位,阀元件20的振动由位移产生为 触发器 因此,位于最靠近阀座181的位置的阀元件20与阀座181之间的通道面积被设定为孔口180的通过面积以下。 因此,仅使用在阀元件20的提升区域中流体力相对于升程变化量的变化量大的提升区域,使得阀元件20由于轻微变化而发生大的位移 可以避免磁吸引力,并且可以抑制阀元件20的振动。
