Description
上記の実施形態では、テーパ角θを38°に設定しているが、35°以上40°以下の範囲に設定しても同様の効果を得ることができる。テーパ角θを縮小することで、より一層、組付性が良好となる。
10…作動棒、10a…太軸部、10b…細軸部、10c…テーパ部、
11…リング状防振バネ部材。
Claims (1)
- 蒸発器(6)出口側の低圧冷媒の温度と圧力とに対応して作動する過熱度応動機構(9)と、
前記過熱度応動機構(9)に連動して作動する作動棒(10)と、
前記蒸発器(6)入口側に設けられ、前記作動棒(10)の軸方向に伸びるように形成された絞り通路(7)と、
前記作動棒(10)によって前記絞り通路(7)の開口面積を調整する弁体(8)と、
前記作動棒(10)に拘束力を付与するリング状防振バネ部材(11)と、
前記絞り通路(7)出口側に設けられ、前記作動棒(10)の軸方向に直交する方向に伸びるように形成されて前記絞り通路(7)通過後の冷媒を前記蒸発器(6)入口側に流入させる冷媒通路(5c)とを備え、
前記リング状防振バネ部材(11)は、弾性を有する環状部(11a)と、該環状部(11a)から内方へ切り起こされるとともに前記作動棒(10)に対して径方向の拘束力を付与する複数の防振バネ(11b)とを有しており、
前記作動棒(10)は、前記リング状防振バネ部材(11)が嵌合される太軸部(10a)と、前記弁体(8)と接触する細軸部(10b)と、前記太軸部(10a)と前記細軸部(10b)とを接続するテーパ部(10c)とを有しており、
前記テーパ部(10c)は、前記冷媒通路(5c)内に位置付けられており、
前記作動棒(10)の軸方向と前記テーパ部(10c)のテーパ面とのなすテーパ角(θ)が、35°以上かつ40°以下であって、
前記弁体(8)が前記絞り通路(7)入口を閉弁しているときの前記作動棒(10)の軸方向断面において、前記太軸部(10a)と前記テーパ部(10c)との接続部から、前記テーパ面が形成する直線と前記絞り通路(7)から噴出した冷媒が衝突する側の前記冷媒通路(5c)の内壁面との交点へ至る距離を衝突距離(A)としたときに、前記衝突距離(A)が2mm以上になっていることを特徴とする膨張弁。
