Abstract
Provided is a lubricant feed mechanism for a turbocharger, the mechanism that can reduce work of an oil pump while preventing an excessive supply of lubricant to a bearing part. The lubricant feed mechanism for a turbocharger, the mechanism of feeding lubricant to a bearing part that rotatably supports a shaft connecting a compressor wheel and a turbine wheel, includes: an oil supply passage that guides the lubricant fed under pressure from the oil pump to the bearing part; and a flow control valve provided to the oil supply passage for adjusting the amount of the lubricant by throttling the flow passage of the lubricant based on a pressure of the lubricant flowing through the oil supply passage.
