Patent ID: 8695336

Claim:
An internal combustion engine comprising: at least one turbocharger having an exhaust gas inlet, a compressor, and a turbine; an exhaust gas system having an exhaust gas channel which is connected to the exhaust gas inlet; and a valve in the exhaust gas system, a position of the valve being controlled in response to a characteristic indicative of a charge pressure of combustion air, the valve including: a valve member configured for regulating exhaust gas directed to the turbine, a first moveable control member operatively connected to the valve member such that a position of the first control member is correlated with a position of the valve member, the position of the first control member being at least partially dependent on at least a force exerted on the first control member by a gas having a pressure that is indicative of the charge pressure of combustion air and a first reference force exerted on the first control member so as to control the position of the valve in a first range of the characteristic indicative of the charge pressure of combustion air, the gas being supplied from downstream of the compressor, the first reference force being supplied by a first reference pressure source, and a second moveable control member operatively connected to the valve member such that a position of the second control member is correlated with the position of the valve member, the position of the second control member being at least partially dependent on at least a force exerted on the second control member by the gas having the pressure that is indicative of the charge pressure of combustion air and a second reference force exerted on the second control member so as to control the position of the valve in a second range of the characteristic indicative of the charge pressure of combustion air, the second reference force being supplied by a second reference pressure source; wherein the first reference pressure source is different the second reference pressure source, and wherein the first control member is directly coupled to the valve member via a valve spindle, the first control member is mounted in an inner housing, and the inner housing is directly connected with the second control member which is moveable in an outer housing.
