Abstract
【解決手段】モータの回転を弁軸の直線運動に変換する機構に於いて、弁軸上端21cにワッシャ形式の軸受部材51を嵌着し、弁軸上端21cのカシメ加工により軸受部材51を回動不動に弁軸上端21cに固着し、弁軸と軸受部材51の相対運動を防止すると共に、嵌着部の摩耗を防止する。

Claims (2)
- 円筒状の外周面にネジ部を有し、このネジ部が本体側に螺合され、モータで回転されるとネジ部の作用により軸心方向に移動する可動部材と、この可動部材を可動部材の軸心に沿って一端側が貫通し、可動部材に対して回転方向には拘束されないが軸心方向には拘束される弁軸とを有し、弁軸の他端に弁体を取り付け、可動部材が移動することにより弁軸と共に弁体を移動させて開度を変化させる流量制御弁において、上記弁軸の一端側を他の部分より細くして貫通部を形成し、この貫通部と他の部分との間に形成される段部に上記可動部材の一方の端面を当接させ、可動部材の他方の端面と弁軸の一端である貫通部の端部との間にスラスト軸受部を設けて可動部材が貫通部から抜けないようにしたものであって、このスラスト軸受部を構成する1対の軸受部材のうち、貫通部の端部側の軸受部材を弁軸の貫通部に対して回転しないように固定したことを特徴とする流量制御弁。
- 上記軸受部材のうち、上記弁軸の貫通部に対して固定される側の軸受部材の外径と、可動部材側の軸受部材の外径とを相違させ、両軸受部材の段差部分にグリス溜まりを形成したことを特徴とする請求項1に記載の流量制御弁。
