Metering device for adjusting and/or controlling a gas flow, method for adjusting and/or controlling a gas flow, and domestic appliance assembly

A domestic appliance assembly comprising:

• a domestic appliance and a metering device for adjusting and/or controlling a gas flow, wherein a mass flow of gas in a range of from 0 to about 10 g/min can be adjusted by the metering device, wherein the metering device comprises an electrically activatable valve, wherein the gas flow through the metering device can be adjusted and/or controlled by means of the electrically activatable valve,
• wherein the metering device has a pressure sensor, wherein a gas pressure difference across a gas passage opening of the metering device can be measured by means of the pressure sensor, wherein the electrically activatable valve can be adjusted in dependence on the measured gas pressure difference;
• and
• 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 adjusted by means of the adjustable pressure control device, wherein the gas flow through the metering device, which can be adjusted by means of the electrically activatable 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 that is adjusted by means of the adjustable pressure control device wherein the maximum gas pressure difference between the inlet region of the metering device and the outlet region of the metering device that can be adjusted by means of the adjustable pressure control device corresponds to a specifiable maximum value of between 0.01 bar inclusive and 2.00 bar inclusive.
