Description
上記課題を解決するオイルセパレータは、筐体と前記筐体内に設けられた衝突材とを備え、油分を含む空気を前記筐体内に導入して前記衝突材に衝突させることによって、導入された空気から油分を分離してドレン溜め部に回収するオイルセパレータにおいて、前記空気から分離して回収した油分を含むドレン液を、外部装置に還元するドレン還元装置を備え、前記ドレン還元装置は、前記ドレン溜め部に接続される流入口と、前記流入口から流入したドレン液を収容する収容部と、前記外部装置に接続される吐出口と、を備え、前記収容部を加圧することで、収容されたドレン液を前記吐出口から前記外部装置に吐出することをその要旨としている。
上記構成によれば、エアドライヤのエキゾストバルブを制御するコントロールエアによってピストンを変位させる。このため、エアドライヤのガバナを動作させるとき、ドレン還元装置から外部装置にドレン液を吐出することができる。よって、ドレン液の吐出を、エアドライヤの排出と同一回数行うことができる。
上記構成によれば、エアドライヤのエキゾストバルブを制御するコントロールエアによって収容部内のドレン液を吐出させる。このため、エアドライヤのエキゾストバルブを動作させるとき、すなわちエアドライヤから油分を含む空気がオイルセパレータに導入されるときに、ドレン還元装置から外部装置にドレン液を吐出することができる。よって、ドレン液の吐出を、エアドライヤの排出と同一回数行うことができる。
上記構成によれば、オイルセパレータから排出される排出空気によって収容部内のドレン液を吐出させる。このため、ドレン液の吐出を、オイルセパレータから排出空気の排出と同一回数行うことができる。
上記構成によれば、オイルセパレータのドレン溜め部に溜まったドレン液を外部装置において使用することでドレン液を消費して、オイルセパレータが空気から分離して溜めたドレン液の回収作業の回数を極力抑制することができる。
以下、図1及び図2を参照して、オイルセパレータ及び車両用油分分離システムの第1の実施形態について説明する。
図1に示されるように、コンプレッサ1は、エンジン6の駆動によって圧縮空気を発生させて、エアドライヤ2に圧縮空気を送出する。エアドライヤ2は、コンプレッサ1から導入された圧縮空気を乾燥剤に通過させて、圧縮空気に含まれる水分や油分を除去するロード運転を行い、乾燥圧縮空気をシステムタンク4に送出する。システムタンク4は、各システムに圧縮空気を供給する。一方、システムタンク4の圧力が所定値に達し、ガバナによってエアドライヤ2にコントロールエアが導入されると、エアドライヤ2は、乾燥剤を再生させるアンロード運転を行う。アンロード運転時には、エアドライヤ2は、圧縮空気を逆流させて、ドレン排出口2bから水分とともに油分も含まれるパージエアを送出する。エアドライヤ2のドレン排出口2bから送出されたパージエアは、エアドライヤ接続ホース20を介してオイルセパレータ3に導入される。エアドライヤ2に導入されたコントロールエアは、エアドライヤ2で使用された後、コントロールエア供給ホース21を介してドレン還元装置10の供給口17から供給される。
(1)オイルセパレータ3のドレン溜め部3cに溜まったドレン液をドレン還元装置10によってエンジン6のオイルパン6aに還元することができる。すなわち、ドレン還元装置10は、オイルセパレータ3のドレン溜め部3cから流入口12を介してドレン液を収容部13に収容して、収容部13を加圧することで、収容部13に収容されたドレン液を吐出口14からエンジン6のオイルパン6aに吐出する。このため、オイルセパレータ3のドレン溜め部3cに溜まったドレン液をドレン還元装置10によってエンジン6のオイルパン6aに還元することで、オイルセパレータ3が空気から分離して溜めたドレン液の回収作業の回数を抑制することができる。
以下、図4を参照してオイルセパレータ及び車両用油分分離システムの第2の実施形態について説明する。この実施形態のオイルセパレータは、吐出エアとしてコントロールエアに替えてシステムエアを使用する点が上記第1の実施形態と異なっている。以下、第1の実施形態との相違点を中心に説明する。
(6)エアドライヤ2のエキゾストバルブ2aを制御するコントロールエアによってシステムタンク4のシステムエアを収容部13内に供給させて、ピストン18を変位させるので、コントロールエアのみによるピストン18の駆動よりも大きな力でピストン18を確実に変位させることが可能となる。また、エアドライヤ2から油分を含む空気がオイルセパレータ3に導入されるときに、ドレン還元装置10からエンジン6のオイルパン6aにドレン液を吐出することができるので、ドレン液の吐出を、エアドライヤ2の排出と同一回数行うことができる。
以下、図5を参照して、オイルセパレータ及び車両用油分分離システムの第3の実施形態について説明する。この実施形態のオイルセパレータは、ドレン還元装置にピストンを備えず、エアのみの作用によってドレン液を吐出する点が上記第1の実施形態と異なっている。以下、第1の実施形態との相違点を中心に説明する。
(7)ドレン還元装置100の供給口117からコントロールエアが供給されて、収容部113に収容されたドレン液を吐出口114からエンジン6のオイルパン6aに吐出する。このため、ピストン等の駆動構造を備えることなく、そのため、構成を容易にすることができる。
以下、図6を参照して、オイルセパレータ及び車両用油分分離システムの第4の実施形態について説明する。この実施形態のオイルセパレータは、コントロールエアに替えてオイルセパレータの排出空気(清浄エア)を使用する点が上記第3の実施形態と異なっている。以下、第3の実施形態との相違点を中心に説明する。
(9)オイルセパレータ3から排出される清浄エアによって収容部113内のドレン液を吐出させる。このため、ドレン液の吐出を、オイルセパレータ3から清浄エアの排出と同一回数行うことができる。
以下、図7を参照して、オイルセパレータ及び車両用油分分離システムの第5の実施形態について説明する。この実施形態のオイルセパレータは、吐出エアを使用せず、加熱によって収容部を加圧する点が上記第1の実施形態と異なっている。以下、第1の実施形態との相違点を中心に説明する。
(10)ドレン還元装置200の容器200a内のドレン液が加熱によって膨張することで容器200a内を加圧すると、ドレン液がドレン還元装置200からエンジン6のオイルパン6aに吐出される。このため、容器200aに圧縮空気を供給するための供給路を設置することなく、加熱部201のみによってドレン液をドレン還元装置200からエンジン6のオイルパン6aに吐出することができる。
・上記実施形態では、流入口12とドレン供給ホース30との接続に螺合を採用したが、螺合に限らず、スナップフィット等の他の接続を採用してもよい。
・上記実施形態では、第1接続部材16とエンジン接続ホース60との接続に螺合を採用したが、螺合に限らず、スナップフィット等の他の接続を採用してもよい。
・上記実施形態では、供給口17と第2接続部材19との接続に螺合を採用したが、螺合に限らず、スナップフィット等の他の接続を採用してもよい。
・上記実施形態では、供給口17とコントロールエア供給ホース21との間に第2接続部材19を設けたが、供給口17とコントロールエア供給ホース21とを直接接続してもよい。
・上記実施形態では、油を使用する外部装置にドレン液を還元したが、油を使用しない外部装置にドレン液を還元してもよい。例えば、図8に示されるように、外部装置としてのタンク70にタンク接続ホース71を介してドレン還元装置10が接続されている。タンク70は例えばサイドガード72に固定されている。よって、オイルセパレータ3のドレン溜め部3cに溜まったドレン液がドレン還元装置10によってタンク70に還元される。タンク70に溜まったドレン液は例えば満量になる前に定期的に廃棄する。
