  • Lubricating device for engine-driven supercharger
    Patent number: 5377649
    Abstract: Oil feed and discharge lines (34) and (35) are respectively connected between an engine (15) and an external oil feed type engine-driven supercharger (I) so as to circulate a lubricating oil (0) between them. The lubricating oil (0) used in the engine (15) is fed through the oil feed line (34) to the supercharger (I) while the lubricating oil (0) used in the supercharger (I) is returned through the oil discharge line (34) to the engine (15). As a result, the lubricating oil and associated parts exclusively for the supercharger can be eliminated.
