Description
本明細書において、弁体3から作動棒6に向かう方向を「上方向」と定義し、作動棒6から弁体3に向かう方向を「下方向」と定義する。よって、本明細書では、膨張弁1の姿勢に関わらず、弁体3から作動棒6に向かう方向を「上方向」と呼ぶ。
図1乃至図4を参照して、実施形態における膨張弁1について説明する。図1は、実施形態における膨張弁1の全体構造を模式的に示す図である。図2は、防振ばね7の一例を模式的に示す概略斜視図である。図3は、膨張弁1の開度が微小であるときの防振ばね7の状態を模式的に示す図である。図4は、膨張弁1の開度が比較的大きいときの防振ばね7の状態を模式的に示す図である。
図2を参照して、実施形態における防振ばね7の一例について説明する。図2に記載の例では、防振ばね7は、複数の弾性突出部77を備えたリングばね7Bである。なお、図2に記載の例では、弾性突出部77の個数は3個であるが、弾性突出部77の個数は、4個以上であってもよい。
図5を参照して、膨張弁1の適用例について説明する。図5は、実施形態における膨張弁1を冷媒循環システム100に適用した例を模式的に示す概略断面図である。
