Abstract
Description
- SMAワイヤの構成:最も有用な構成のうち、単一のSMAワイヤが、好ましくは一方の端部が固定面に固定されると共に他方の端部が変形可能要素に固定された直線状の形態で利用される。代替的には、SMAワイヤは、両端部が固定面に固定されると共に中央部が変形可能要素に固定/接続された、いわゆるV/U字状の構成で利用される。
- 弁のタイプ:弁自体は、単純なオン/オフ弁又は比例弁とされる。
- 弁ポート:弁は,入口及び出口に対応する2つの弁ポートを具備する単純な2方向弁であっても良いが(図1~図3)、さもなければ、3方向弁(図4)を形成するために3つのポート又はより多くのポートを具備する一層複雑な構成を有していても良い。
- 変形可能要素:本発明は、特定のタイプの変形可能要素に限定される訳ではないが、蛇腹部や膜、特に波状の膜が望ましい。
- 変形可能要素の材料:好ましい材質は柔軟な金属であるが、プラスチックやシリコンも使用可能である。
- 位置フィードバック:ホール効果センサ及び磁石の利用が望ましいが、例えばSMA抵抗制御やピストン及びプランジャのような他の手段であっても良い。幾つかの場合には、これら2つの要素は、1つの要素に組み込まれており、膜の場合には、この共通する要素の中央部分が、膜の曲率を変更するために変形可能要素に拘束されている。
- バイパスチャネル:バイパスチャネルの断面積と弁ポートの断面積との好ましい比率は、0.1~1とされる。これにより、弁全体の流量に対して最良のバイパスの平衡流量を確保することができる。
