LUBRICATING OIL SUPPLY MECHANISM FOR TURBOCHARGER

PROBLEM TO BE SOLVED: To provide a lubricating oil supply mechanism for a turbocharger, capable of suppressing the temperature rise of a flow control valve.SOLUTION: A lubricating oil supply mechanism 1 for a turbocharger 6 supplies lubricating oil to a bearing part 41 of the turbocharger 6 of an engine E. It includes a lubricating oil supply oil path (a forcible feed oil path 3 and a supply oil path 42) for guiding the lubricating oil to the bearing part 41, a lubricating oil discharge oil path (a discharge oil path 43 and a return oil path 7) for guiding the lubricating oil discharged from the bearing part 41, and a flow control valve 100 provided in the lubricating oil supply path at its position of no overlap with the lubricating oil discharge oil path for throttling the flow path of the lubricating oil distributing in the lubricating oil supply oil path to control the flow of the lubricating oil.SELECTED DRAWING: Figure 1 【課題】流量制御弁の温度上昇を抑制することが可能なターボチャージャの潤滑油供給機構を提供する。【解決手段】エンジンＥに設けられたターボチャージャ６の軸受部４１へと潤滑油を供給するターボチャージャ６の潤滑油供給機構１であって、潤滑油を軸受部４１へと案内する潤滑油供給油路（圧送油路３及び供給油路４２）と、軸受部４１から排出される潤滑油を案内する潤滑油排出油路（排出油路４３及び戻り油路７）と、前記潤滑油供給油路に設けられると共に、前記潤滑油排出油路と重複しない位置に設けられ、前記潤滑油供給油路を流通する潤滑油の流路を絞ることによって当該潤滑油の流量を調節する流量制御弁１００と、を具備した。【選択図】図１
