- 電動モータのロータの回転運動をこのロータ側に形成された雌ねじとこのロータの中心に該雌ねじと同軸に配置された雄ねじとのねじ送り機構によって、作動軸を直線運動に変換し、この作動軸に配置された弁体を弁シートに対して移動して弁の開閉を行う電動弁において、
前記雌ねじを構成する部材と前記雄ねじを構成する部材とを、前記雌ねじの軸方向に垂直な方向の線膨張率が、前記雄ねじの軸方向に垂直な方向の線膨張率より大きくなるような材質によりそれぞれ形成したことを特徴とする電動弁。 - 前記雌ねじの軸方向の線膨張率と前記雄ねじの軸方向の線膨張率とが同等となる材質により、前記雌ねじを構成する部材と前記雄ねじを構成する部材とをそれぞれ形成したことを特徴とする請求項1に記載の電動弁。
- 前記雌ねじを構成する部材を、樹脂材料を基材としてこの樹脂材料に繊維状のフィラーを前記雌ねじの軸方向と同一の方向となるように混入したことを特徴とする請求項1に記載の電動弁。
