| description | PROBLEM TO BE SOLVED: To provide a pressure adjustment mechanism in a turbocharger which properly adjusts a pressure in an oil catch tank of the turbocharger without causing leakage of a blow-by gas when an engine is stopped to properly prevent leakage of a lubrication oil to an exhaust pipe and an air intake duct.SOLUTION: A pressure adjustment mechanism in a turbocharger includes: a turbocharger 10 including a bearing housing 40 for housing a shaft 13 and a bearing 14 which connect a compressor wheel 12 with a turbine wheel 11, and an oil catch tank 16 which recovers and stores a lubrication oil O; and pressure adjustment passages 41 which allow communication between an internal space A of the oil catch tank 16 and a scroll chamber 31 of a compressor housing 30. The pressure adjustment passages 41 are formed as ventilation passages which respectively open to the internal space A of the oil catch tank 16 and the interior of the scroll chamber 31 and formed in the compressor housing 30 and the bearing housing 40.SELECTED DRAWING: Figure 2
【課題】ブローバイガスの漏出を生じることなく、エンジン停止時にターボチャージャのオイルキャッチタンク内の圧力を的確に調整して潤滑油の排気管や吸気ダクトへの漏出を的確に防止することが可能なターボチャージャ内の圧力調整機構を提供する。【解決手段】ターボチャージャ内の圧力調整機構は、コンプレッサホイール１２とタービンホイール１１とを連結するシャフト１３や軸受１４を収容するベアリングハウジング４０と、潤滑油Ｏを回収して貯蔵するオイルキャッチタンク１６とを備えるターボチャージャ１０と、オイルキャッチタンク１６の内部空間Ａとコンプレッサハウジング３０のスクロール室３１とを連通する圧力調整路４１とを備え、圧力調整路４１は、オイルキャッチタンク１６の内部空間Ａとスクロール室３１内に向けてそれぞれ開口し、コンプレッサハウジング３０内およびベアリングハウジング４０内に形成された通気路として形成されている。【選択図】図２ |
