LUBRICATING OIL FEED MECHANISM OF TURBOCHARGER

摘要

PROBLEM TO BE SOLVED: To provide a lubricating oil feed mechanism of a turbocharger that can reduce the work of an oil pump while preventing excessive lubricating oil from being fed to a bearing part.SOLUTION: A lubricating oil feed mechanism of a turbocharger 5 feeds lubricating oil to a bearing part 41 that rotatably supports a shaft 10 to which a compressor wheel and a turbine wheel are connected, and comprises: an oil feed passage 42 that leads the lubricating oil pumped from an oil pump to the bearing part 41; and a flow control valve 50 that is provided in the oil feed passage 42 and adjusts a flow rate of the lubricating oil by throttling a flow passage of the lubricating oil on the basis of a pressure of the lubricating oil flowing through the oil feed passage 42.
