- 自動車の内燃機関用の冷却回路であって、
内燃機関(10)と、
前記内燃機関(10)の上流に配置され、前記内燃機関を通じて冷却液を送り込むためのポンプ装置(12)と、
前記冷却液を冷やすために、その入口側が第一の冷却液ライン(18)によって内燃機関(10)の出口側に接続され、その出口側が第二の冷却液ライン(20)によって前記ポンプ装置(12)の入口側に接続されているラジエータ(14)と、
前記ラジエータ(14)をバイパスしながら内燃機関(10)の出口側をポンプ装置(12)の入口側に直接接続するラジエータバイパスライン(22)と、
前記第二の冷却液ライン(20)及び前記ラジエータバイパスライン(22)を選択的に開閉するために、前記ラジエータ(14)と前記ポンプ装置(12)の間の前記第二の冷却液ライン(20)に配置された切換え弁(24)とを有し、切換え弁バイパスダクト(44)が備えられ、該切換え弁バイパスダクト(44)が前記切換え弁(24)をバイパスしながら前記第二の冷却液ライン(20)を前記ポンプ装置(12)の入口側へ直接接続し、バルブ装置(46)が前記切換え弁バイパスダクト(44)に追加的に配置され、該バルブ装置(46)が常に前記ポンプ装置(12)の入口側から前記第二の冷却液ライン(20)への冷却液の還流を防止し、
前記切換え弁バイパスダクト(44)の前記バルブ装置(46)が、前記内燃機関(10)が停止しているときに前記第二の冷却液ライン(20)から前記ポンプ装置(12)の入口側への直接接続を開き、そして前記バルブ装置の両側の差圧が所定のしきい値を超えたときに前記直接接続を閉じることを特徴とする冷却回路。 - 前記所定のしきい値が約0.1バールと約0.3バールの間の範囲内で選択されることを特徴とする請求項1に記載の冷却回路。
- 前記切換え弁(24)がサーモスタットバルブであることを特徴とする請求項1あるいは2に記載の冷却回路。
