TURBOCHARGER

摘要

PROBLEM TO BE SOLVED: To provide a turbocharger with oil-cooling structure that can be installed on a water bike. SOLUTION: An oiling passage 9 for feeding oil O to a journal bearing 7 supporting a turbine shaft 6 is provided in a bearing casing 3 between a turbine casing 1 and a compressor casing 2. A cooling jacket 10 is formed at a position close to the turbine casing 1 in the bearing casing 3. The fueling passage 9 is connected to a branch passage 11, which communicates with the cooling jacket 10. The branch passage 11 has an orifice 11a. The oil O flows from the oiling passage 9 to the cooling jacket 10 through the branch passage 11 to cool the bearing casing 3. COPYRIGHT: (C)2004,JPO
