Description
図2に示されるように、開閉弁16は、パイロット流路Wpと、主弁160と、ダイヤフラム161と、パイロット弁162とを備えている。開閉弁16は、第3流路W3を構成する配管170、及び第4流路W4を構成する配管171と一体化されている。
ポンプ14が駆動している状況において仮にパイロット弁162が閉弁状態である場合、第3流路W3の上流側接続点C2の流路内圧P1が背圧室167に加わる。この際、主弁流入口164の流路内圧P2と背圧室167の内部圧力P3とが等しいため、ダイヤフラム161の主弁流入口164側の面及び背圧室167側の面には等しい圧力が加わる。ダイヤフラム161では、主弁流入口164側の受圧面積よりも背圧室167側の受圧面積の方が大きいため、背圧室167から弁収容室163に向かう方向の押圧力がダイヤフラム161に加わる。この押圧力により、図3に示されるように、ダイヤフラム161が背圧室167から弁収容室163に向かう方向に弾性変形し、開閉弁16が閉弁状態になる。この状況では、第3流路W3の上流側接続点C2の流路内圧P1、主弁流入口164の流路内圧P2、背圧室167の内部圧力P3、主弁流出口166の流路内圧P4、及び第4流路W4の下流側接続点C3の流路内圧P5のそれぞれの値は図4に丸で示されるようになる。
・図6に示されるように、エンジン冷却システム1は、エンジン2とラジエータ10との間のみで熱冷媒が循環する構成からなるものであってもよい。詳しくは、図6に示されるエンジン冷却システム1では、第1流路W1にパイロット式の開閉弁16が設けられている。パイロット流路Wpは、第1流路W1と第2流路W2とを連通させている。また、エンジン冷却システム1には、パイロット流路Wpとは別に、第1流路W1と第2流路W2とを連通させる第5流路W5が設けられている。このエンジン冷却システム1では、ラジエータ10が機器に相当する。また、第1流路W1が供給流路に相当し、第2流路W2が排出流路に相当する。このエンジン冷却システム1では、ECU18がパイロット弁162を閉弁させると、開閉弁16が閉弁状態となる。よって、エンジン2からラジエータ10への熱媒体の流れが遮断される。この場合、エンジン2から排出される熱媒体は、ラジエータ10を流れずに、第5流路W5及び第2流路W2を介してエンジン2にそのまま戻る。すなわち、熱媒体がエンジン2をショートサーキットする。これにより、エンジン2の早期の暖気が可能となる。また、ECU18がパイロット弁162を開弁させると、開閉弁16が開状態となる。よって、エンジン2とラジエータ10との間を熱媒体が循環するため、エンジン2を効果的に冷却させることができる。このような構成であっても、上記実施形態に準じた作用及び効果を得ることができる。
・パイロット弁162は、電磁弁に限らず、モータ駆動弁であってもよい。
