  • Publication number: 20100310365
    Abstract: A turbocharger includes an exhaust nozzle arranged between a scroll passage of a turbine housing and a turbine impeller, a gap formed between a rear surface of the exhaust nozzle and the turbine housing, and a sealing device for closing the gap. The sealing device includes a seal member which is C-shaped, i.e., an annulus with a part cut out to provide a slit, and has an inner peripheral end arranged along the turbine housing. The seal member is configured such that, by action of gas pressure in the scroll passage, the outer peripheral end approaches the rear surface of the exhaust nozzle, slit ends approach to each other, and the inner peripheral end approaches the turbine housing, leading to reduction in diameter. With a simple structure, gas is prevented from leaking from higher to lower pressure sides through a gap between a turbine housing and an exhaust nozzle.
