EXHAUST-GAS TURBOCHARGER HAVING A BYPASS VALVE |
摘要 |
<p>An exhaust-gas turbocharger is embodied with a bypass valve which is disposed in a bypass duct of a turbine between an exhaust-gas pressure line and an outlet cross section of the turbine of the exhaust-gas turbocharger and which is connected to an actuating device for controlling the throughput of exhaust-gas through the bypass duct. Through the bypass valve, a partial flow of the exhaust-gas can be guided past the turbine on demand. The bypass valve has a valve head and a valve stem. The bypass valve is axially movably held with the valve stem. The valve head, in a closed state of the bypass valve, can be placed against a valve seat in order to close the bypass duct in a gas-tight and pressure-tight manner. The side of the valve head that is connected to the valve stem faces the exhaust-gas pressure line.</p> |
