Abstract
【解決手段】膨張弁1aは弁本体10に設けられる高圧の液冷媒が供給される入口ポート20を有する。冷媒は小径部21を介して弁室22に流入し、弁体60と弁座24の弁通路を通り、オリフィス26、出口ポート28からエバポレータへ送られる。弁体駆動装置40は、作動棒50を介して弁体60を操作して弁開度を制御する。弁体60はばね受け100を介して付勢ばね80により支持される。ばね受け100は、付勢ばね80の内部に挿入される円柱状の垂下体110を備え、冷媒が付勢ばね80の内部に流入するのを防止する。この作用により冷媒の流れの乱れは防止され、騒音の発生原因は除去される。

Description
膨張弁1は弁本体10を有し、弁本体10には、コンプレッサ側から供給される高圧の冷媒が導入される入口ポート20が設けられ、入口ポート20は小径部21を介して弁室22に連通する。入口ポート20には弁体60により開閉される弁座24が形成され、弁座24と弁体60により流量が制御された冷媒はオリフィス26を通り、出口ポート28からエバポレータ側へ送り出される。
弁体駆動装置40は作動流体が封入される作動圧力室を有し、圧力の変動はダイアフラムの変位に変換されて作動棒50に伝達される。
この種の膨張弁は下記の特許文献1に開示されている。
そこで本発明の目的は、上述した不具合を解消する膨張弁を提供することにある。
