Abstract:
1. An exhaust-gas turbocharger, comprising: a turbine having an outlet cross section; an exhaust gas pressure line; a bypass duct; a bypass valve disposed in said bypass duct between said exhaust-gas pressure line and said outlet cross section of said turbine; a valve seat, said bypass valve having a valve head and a valve stem, said bypass valve being axially movably held with said valve stem; said valve head, in a closed state of said bypass valve, being placeable against said valve seat in order to close said bypass duct in a gas-tight and pressure-tight manner; said valve head having a side connected to said valve stem, said side of said valve head connected to said valve stem facing said exhaust-gas pressure line; an actuating device, said bypass valve being connected to said actuating device for controlling a throughput of exhaust-gas through said bypass duct, such that, through said bypass valve, a partial flow of the exhaust-gas is guidable past said turbine on demand; a housing having a recess formed therein; and a pressure plate disposed at said bypass valve, said pressure plate being movable in said recess of said housing.
