Abstract
The invention relates to a metering device for adjusting and/or controlling a gas flow, characterised in that the metering device comprises an electrically controllable valve, wherein the gas flow through the metering device can be adjusted and/or controlled by means of the electrically controllable valve,—wherein the metering device has a pressure sensor, wherein a gas pressure difference across a gas-outlet opening in the metering device can be measured by means of the pressure sensor, wherein the electrically controllable valve can be adjusted according to the measured gas pressure difference; and/or—wherein the metering device comprises an adjustable pressure-control device, wherein a maximum gas pressure difference between an inlet region of the metering device and an outlet region of the metering device can be set by means of the adjustable pressure-control device, wherein the gas flow through the metering device, which gas flow can be adjusted by means of the electrically controllable valve, is limited by the maximum gas pressure difference between the inlet region of the metering device and the outlet region of the metering device which is set by means of the adjustable pressure-control device.
