Description

前記ステップモータ１３は、前記弁体ガイド孔１０の軸線と同軸にして前記スリーブ１８内に配置されるモータ軸１９を有しており、このモータ軸１９の外周に設けられる雄ねじ２０が、前記弁体ガイド孔１０内に同軸に配置される円筒状のナット２１に螺合される。しかも前記ナット２１の前記ステップモータ１３側の端部には半径方向外方に張り出して前記スリーブ１８内に摺動可能に嵌合されるフランジ部２１ａが設けられており、そのフランジ部２１ａの外周から突出される突部２２が、前記スリーブ１８の内周に設けられて該スリーブ１８の軸方向に延びる係止溝２３に係合される。したがってナット２１の回転は阻止されており、ステップモータ１３の作動に応じた前記モータ軸１９の回転によって前記ナット２１が軸方向に移動することになる。 The step motor 13 has a motor shaft 19 disposed in the sleeve 18 coaxially with the axis of the valve element guide hole 10, and a male screw 20 provided on the outer periphery of the motor shaft 19 It is screwed into a cylindrical nut 21 disposed coaxially in the body guide hole 10. Moreover the step at the end of the motor 13 side and the flange portion 21a which is slidably fitted into the sleeve 18 projects radially outwardly is provided, the outer periphery of the flange portion 21a of the nut 21 A protrusion 22 protruding from the sleeve 18 is engaged with a locking groove 23 provided on the inner periphery of the sleeve 18 and extending in the axial direction of the sleeve 18. Therefore, the rotation of the nut 21 is prevented, and the nut 21 is moved in the axial direction by the rotation of the motor shaft 19 according to the operation of the step motor 13.

前記弁体ガイド孔１０には、合成樹脂から成る弁体２７が摺動可能に嵌合されるものであり、この弁体２７は、外周を前記弁体ガイド孔１０の内周に摺接される大径部２７ａと、前記スリーブ１８内に挿入されるようにして前記大径部２７ａに連なる小径部２７ｂとを一体に有しており、前記フランジ部２１ａを除いて前記ナット２１を同軸に囲繞するとともに前記止め輪２６よりも上方で前記弁体支持部材２５を同軸に囲繞するようにして段付き円筒状に形成される。 A valve body 27 made of synthetic resin is slidably fitted into the valve body guide hole 10, and the valve body 27 is slidably contacted with the inner periphery of the valve body guide hole 10. A large-diameter portion 27a and a small-diameter portion 27b connected to the large-diameter portion 27a so as to be inserted into the sleeve 18, and the nut 21 is coaxially formed except for the flange portion 21a. The valve body support member 25 is formed in a stepped cylindrical shape so as to surround and coaxially surround the valve body support member 25 above the retaining ring 26.
