    • PROBLEM TO BE SOLVED: To provide a solenoid driving valve and a high-speed response solenoid which allow sufficient driving output and sufficient operation speed to be obtained. SOLUTION: A solenoid for the solenoid driving valve comprises a bobbin having a cross section of generally rectangular or elliptical shape, a polar plate fixed to the bobbin, and an armature which can slide within the bobbin in response to a magnetic field generated through the plate by a coil. The coil wound around the bobbin has a cross section of generally rectangular shape, and its minor-axis side is a width W. A ratio (D/W) of a diameter D to the width W is constituted to be in the range of 0.4-0.8, where D is a diameter of a cylindrical virtual iron core having the width W and whose cross section is equal to that of the armature. A ratio (A/B) of a major-axis side length A of the armature to a minor-axis side length B of the armature is in the range of 3.1 or more to 4.5 or less. COPYRIGHT: (C)2006,JPO&NCIPI

    • 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
