A method device for controlling a suction pressure of an internal combustion engine, particularly a diesel engine having an exhaust gas turbocharger. The compressor is connected to a suction line of the internal combustion engine via an actuating section having an actuating element for changing a cross-section of the actuating section. In the first step, the current suction pressure in the suction line of the internal combustion engine is determined. A compressor pressure of the compressor is determined by pressure sensors and compared to the suction pressure. Values corresponding to current operating data of the internal combustion engine are identified and an actuation signal is generated using a controller, based on the comparison; and changing the cross-section of the actuating section is adjusted by adjusting the actuating element using the actuating signals.

A system has a compressor and a consumer which are coupled to a drivetrain and extract energy through the drivetrain. The consumer is suitable for varying an absorption of power, which is made available to it by the drivetrain, as a function of a power which is required for compressor operation and which is supplied from the drivetrain to the compressor. A pump has at least one pump chamber which generates a pumping power during pumping operation. The pump additionally has at least one pump chamber which generates no pumping power or a reduced pumping power during pumping operation.

A compressor system for a vehicle includes a compressor driven by a drive motor of the vehicle and a suction air conduit for supplying air that has already been precompressed by a turbocharger of the drive motor to the compressor. A mechanism is disposed in the suction air guide for reducing the flow cross-section. The mechanism is able to limit the charging pressure of the already precompressed air supplied to the compressor. A method for controlling a compressor system having a turbocharged compressor limits a charging pressure of the already precompressed air to an adjustable maximum value.

An exhaust gas turbocharger for an internal combustion machine, in particular a diesel engine, having an unburnt mixture supply device, includes at least one compressor; at least one exhaust gas turbine; a turbocharger shaft by which the compressor and the exhaust gas turbine are rotationally fixedly coupled; and an energy store for increasing a mass moment of inertia. The energy store is rotationally fixedly coupled to the at least one compressor and the at least one exhaust gas turbine by the turbocharger shaft. An arrangement for supplying unburnt gas to an internal combustion machine includes such an exhaust gas turbocharger and an unburnt gas supply device.
