Description
図4は、本発明手段を実施せる熱動弁Wの正面図、図5は同上の縦断正面図、図6は同上の駆動部の拡大した縦断正面図、図7は同上駆動部の組み立て途上の分解した縦断正面図、図8は同上駆動部の組立てた状態における縦断正面図であり、これら図において、Wは熱動弁、Aはその熱動弁Wのバルブ部、Bは熱動弁Wの駆動部、1はバルブ部Aに組み込まれた弁機構、10はその弁機構1の弁座、11は弁体、12は弁体11を弁座10に衝合させるように付勢するバネ、13は弁体11に設けた弁軸、40は弁機構1を組み込んだ管路を示し、また、20は駆動部Bに組み込まれた発熱体、21・21はその発熱体20の軸方向の一対の盤面のそれぞれに接触させた電極板、22は熱応動素子、23はその熱応動素子22を包み込むよう収蔵する金属材よりなる感温部、24は熱応動素子22の体積変化により出入作動する作動軸、25は作動軸24の出入作動をガイドするよう感温部23の基端側に加締め付けて連結したガイド筒部、30は駆動部Bを収蔵して前述の弁機構1を組み込んだ管路40に組み付ける枠体、31は駆動部Bの作動軸24と弁機構1の弁軸13とを連繋する接続金具、26は発熱体20を挟む一対の電極板21・21のそれぞれに接続するコードを示している。
Claims (2)
- 金属材でケース状に成形して内部に熱応動素子(22)を収蔵せる感温部(23)と、その感温部(23)の基端側に加締め付けにより連結して内腔に前記熱応動素子(22)の温度変化による体積変化により出入作動するよう作動軸(24)が嵌挿されるガイド筒部(25)と、盤状に成形して軸方向の一対の盤面を電極板(21)・(21)で挟み一方の盤面を前記感温部(23)の先端側の端面(23b)に当接させる発熱体(20)と、前記作動軸(24)の出入作動により開閉作動する弁機構(1)と、により構成される熱動弁(W)において、前記金属材で成形する感温部(23)の、先端側の端面(23b)からガイド筒部(25)を加締め付ける加締部(23a)の手前に至る先端側の部分を、前記端面(23b)が当接する発熱体(20)の盤面に対し面積比で50%程度、径比において20%前後を限度とする縮径加工により前記発熱体(20)の盤面よりも小径に成形した熱動弁。
- 金属材で筒状に成形して感温部(23)に加締め付けるガイド筒部(25)の、先端部を残した胴部を、外周側からの縮径加工により該ガイド筒部(25)の先端部の外径よりも小径に成形した請求項1記載の熱動弁。
