    • PROBLEM TO BE SOLVED: To dissolve the excessive wear, premature failure and unstable pressure of a valve assembly by providing a circuit for integrating a difference between a pilot pressure feedback signal and an output pressure feedback signal to generate an integrated feedback signal. SOLUTION: A pilot pressure feedback loop 24 is distributed to a pilot pressure line 20 and electrically connected to an electric part 22 in a valve 18 to generate a pilot pressure feedback signal in accordance with a pilot signal. An output pressure feedback loop 30 is distributed to an output port 16 in a booster pressure governor 12 and electrically connected to the electric port 22 in the valve 18 to generate an output pressure feedback signal in accordance with output pressure of the booster pressure governor 12. An integrating circuit 38 integrates a difference between the pilot pressure feedback signal and the output pressure feedback signal to generate an integrated feedback signal. Therefore, the excessive wear, premature failure and unstable pressure of a valve assembly can be dissolved.

    • 【課題】ステッパモータにより駆動する流量制御弁のバルブ位置制御および再現性を向上させる。 【解決手段】流量制御弁10は、長手方向軸26と同軸の向きに延びる本体部14のボア内部にバルブ部材22が摺動自在に配置される。バルブ部材22は、ボアを有する非円形幾何学形状ヘッド62を備える。ドライブアダプタ16は、バルブ部材22の幾何学形状ヘッド62を摺動自在に収容しバルブ部材22の軸回転を防止するヘッド収容キャビティを有する。ステッパモータ18がドライブアダプタ16に接続され、バルブ部材22のボアに係合された軸を漸増的に回転させる。バルブ部材22の第1ピストン28および同径の第2ピストン38によって、バルブ部材22の圧力バランス動作位置が得られる。 【選択図】図3
    • 要解决的问题:提高由步进电机驱动的流量控制阀的阀位控制和再现性。解决方案:在流量控制阀10中,阀构件22可滑动地布置在主体部分14的延伸的孔内 在与纵向轴线26相同的轴线的方向上。阀构件22包括具有孔的非圆形几何头62。 驱动适配器16具有头部存储空间,其以可滑动的方式存储阀构件22的几何头部62,并且防止阀构件22的轴向旋转。止动器电机18连接到驱动适配器16,并且使轴 以逐渐增加的方式接合到阀构件22的孔。 通过具有与阀构件22的第一活塞28相同直径的第二活塞38,可以获得阀构件22的压力平衡操作位置。图3

    • PROBLEM TO BE SOLVED: To provide a normally open solenoid operated modular valve in which a polymer valve body portion is detachably connected to a solenoid body.SOLUTION: A normally open solenoid operated modular valve 10 includes a solenoid body receiving a coil 38 and pole piece 42. An armature/valve member 52 slidably disposed in both of the solenoid body and a valve body portion is engaged with a polymer material thread-in poppet/valve member 16 to hold the armature/valve member 52. A resilient material valve ring 86 is retained on the thread-in poppet-valve member 16. A cylindrical tube portion receives a rod portion of the armature/valve member 52. A biasing member 78 acts against the armature/valve member and thereby acts to normally bias the valve ring 86 away from contact with a valve seat surface created in the valve body portion to define a normally open position of the modular valve 10.
    • 要解决的问题:提供一种常开电磁操作的模块化阀,其中聚合物阀体部分可拆卸地连接到螺线管体。解决方案:常开电磁操作模块化阀10包括接收线圈38的螺线管体和极片 可滑动地设置在螺线管主体和阀体部分中的电枢/阀构件52与聚合物材料螺纹提升阀/阀构件16接合以保持电枢/阀构件52.弹性材料阀环86 被保持在螺纹提升阀构件16上。圆柱形管部分接收电枢/阀构件52的杆部分。偏置构件78作用于电枢/阀构件,从而用于使阀环86正常偏置 远离与在阀体部分中形成的阀座表面接触以限定模块化阀10的常开位置。
