Abstract
Description
具体的には、例えば、サーモスタット装置が自動車におけるエンジンの入口側に配置される場合、サーモスタット装置は、エンジンに冷却液を供給するウォーターポンプに取り付けられる。この場合、ウォーターポンプ側のサーモスタット装置を取り付けるための部材が相手側部材であり、この相手側部材には、サーモスタット装置の脚部及びその内側のサーモエレメント等を挿し込む取付孔が形成されている。この取付孔の大きさは、自由に変更できないことがあり、前述のように、サーモスタット装置の脚62を大きくしたり、脚62の外側に補強用のリブを設けたりすると、相手側部材の取付孔に挿入できなくなる虞がある。
換言すると、相手側部材の取付孔を変更せずにサーモスタット装置の脚62を大きくしたり、脚62の外側に補強用のリブを設けたりすると、脚62の外側に設けられ、サーモスタット装置のハウジングと相手側部材との間をシールするガスケットのシールラインが成立せずに、ガスケットの取付スペースを確保できなくなる虞がある。
さらには、ハウジングと相手方部材との間をシールするガスケットのシールラインは、脚の外側を通るが、その脚の外側以外の部分では、シールラインを内側へ配置できる。このため、ハウジングを小型にでき、サーモスタット装置の軽量化及び取付スペースの省スペース化が可能になる。
一対のフランジ2,2には、それぞれボルト孔2aが形成される。ボルト孔2aには、金属製のスリーブ(符示せず)が圧入され、このスリーブにサーモスタット装置10を相手側部材へ固定するためのボルト(図示せず)が挿通される。このボルト孔2aよりも内側に位置する本体部20の下端開口縁には、開口20cを取り囲むように環状の溝20dが形成され、この溝20dにガスケット25が装着される。
このガスケット25は、サーモスタット装置10と相手側部材との間をシールし、サーモスタット装置10を相手側部材に取り付けた状態で、ハウジング1内を流れる冷却液が外に漏れるのを防止する。本体部20におけるガスケット25よりも内側(内部側)が、ハウジング1の内側である。
このハウジング1の内側に位置する本体部20の下端開口縁の直上部内周に、環状の弁座20bが形成されており、この弁座20bに弁体15が離着座することで、冷却路が開閉される。
そして、エレメントケース30周囲の冷却液の温度が上昇し、内部の熱膨張体が膨張すると、ピストン3がエレメントケース30から退出し、サーモエレメント17が伸長する。反対に、エレメントケース30周囲の冷却液の温度が低下し、内部の熱膨張体が収縮すると、ピストン3がエレメントケース30に進入し、サーモエレメント17が収縮する。このように、サーモエレメント17は、温度に応じて伸縮作動する。
サーモエレメント17の上端に位置するピストン3の先端は、本体部20の内側、頂部に形成された筒状のボス部20aに篏合する。このため、ハウジング1に対するピストン3の上方への移動が阻止される。よって、サーモエレメント17が伸縮作動すると、ハウジング1に対するピストン3の位置は変わらず、エレメントケース30が上下に移動する。
特に、サーモスタット装置10が、エンジンの入口側に配置され、接続口23からラジエータを経由した冷却液が流入する場合には、この接続口側の冷却液の圧力で弁体15が開弁しないよう、コイルスプリング16のセット荷重を大きくする必要があり、脚21を開く方向へ作用する力が大きくなる。よって、このようなエンジン入口側に配置されるサーモスタット装置10に、本発明が適用されるのが特に有効である。しかし、本発明は、エンジン出口側に配置されるサーモスタット装置に適用されても良い。
また、上記構成によれば、リブ22全体が円Cよりも内側に配置されるため、サーモスタット装置10を相手方部材に搭載する際に、リブ22が相手側部材に干渉することがない。よって、上記構成によれば、補強用のリブ22を設けたとしても、サーモスタット装置10の搭載性が低下するのを抑制できる。
さらには、ハウジング1と相手方部材との間をシールするガスケット25のシールラインは、脚21の外側を通るが、その脚21の外側以外の部分では、シールラインを内側へ配置できる。このため、ハウジング1を小型にでき、サーモスタット装置10の軽量化及び取付スペースの省スペース化が可能になる。
なお、本実施の形態では、リブ22の外側面21bが湾曲しているが、この限りではなく、図4中一点鎖線で記載するように、リブ22の外側面22bが、脚21の外側面21bから円Cの内側へ向かうよう傾斜していても良い。このような場合であっても、本実施の形態と同様に、ハウジング1の脚21の開きを抑制できるとともに、サーモスタット装置10の搭載性が低下するのを抑制できる。
さらに、上記構成によれば、脚21の外側面21bとリブ22の外側面22bとを曲線的に繋げることができ、脚21の外側面21bとリブ22の外側面22bとの間に角(エッジ)ができるのを抑制できるので、この角に応力が集中するのを抑制できる。よって、上記構成によれば、脚21の耐久性を高める上で、より有利である。
しかし、リブ22の外側面22bが湾曲する場合、その曲率半径R2は、脚21の外側面21bの曲率半径R1と同じであっても、それより大きくても良く、適宜変更できる。
しかし、リブ22の内側面22cに、窪み部22aを形成しなくてもよく、ハウジング1の素材及び成型方法も適宜変更できる。具体的には、ハウジング1は、金属製であっても良い。また、リブ22の高さ(厚さ)、幅、長さは、荷重負荷又は耐久条件に応じて、適宜変更できる。
