摘要： PROBLEM TO BE SOLVED: To properly lubricate a supercharging compressor of an engine being influenced by operation of an oil pump of the engine, even by using lubricating oil for the engine. SOLUTION: A compressor lubricating oil passage 89 is branched from an engine lubricating oil passage 87 and has a head H between an upper inlet and a lower outlet thereof to provide an oil reserving function. The compressor lubricating oil passage 89 communicates with a portion to be lubricated of a supercharging compressor C of an engine E through a second oil pump P2 that has a less capacity than a first oil pump P1.

摘要： PROBLEM TO BE SOLVED: To surely lubricate a compressor for supercharging without causing an influence on the operation of an oil pump for an engine using engine lubricating oil. SOLUTION: A lubricating oil path 89 for a compressor is branched from a lubricating oil path for an engine. Head H is provided between the upperstream inlet and the downstream outlet to provide the lubricating oil path 89 for the compressor with an oil sump function. The outlet of the lubricating oil path 89 for the compressor is communicated with the lubricating part of a compressor C for supercharging through a second oil pump P2 having capacity smaller than that of an oil pump P1 for the engine E to float and discharge bubbles from the lubricating oil path 89 for the compressor. The dead weight of the lubricating oil on the lubricating oil path 89 for the compressor is added to the inlet port of the second oil pump P2 to eliminate a delay in supplying the lubricating oil to the compressor C from the pump P2.
