The invention relates to a method for feeding a gas to a metallurgical vessel, the gas carrying a component in the gaseous and/or liquid state that can be condensed or evaporated. The gas is fed to the metallurgical vessel via one or more gas feeding devices. The gas speed is continuously increased in a first section in a number of gas feeding devices, and the gas is intimately mixed in a vortex zone with the components that can be condensed or evaporated. The gas speed is substantially maintained constant in a discharge section and the gas that is intimately mixed with the component carried along is blown into the metallurgical vessel. The invention also relates to a gas feeding device for carrying out the inventive method. The inventive method and the inventive gas feeding device allow prevention and/or reduction of nozzle damages.

The invention relates to an internal combustion engine, comprising a fuel tank (36), a tank ventilation line (38) and a Venturi nozzle (30) arranged in a fluid-conducting component (16), the fluid-conducting component (16) and/or the Venturi nozzle (30) have/has an inflow channel (28), an access point (40) connected downstream of the inflow channel (28) and fluidically connected to the tank ventilation line (38), and an outflow channel (32) connected downstream of the access point (40). In this case, an outflow section (48) of the Venturi nozzle (30) downstream of the inlet point (40) is surrounded by a component (16) in such a way that a detection chamber (46) is formed around the outflow section (48), the detection chamber (46) having at least one inflow opening (50) via which the detection chamber (46) can be pressurized, the at least one pressure sensor (76, 84) is arranged and designed to detect a pressure that varies in the tank ventilation line (38) as a result of a leak in the detection chamber (46).
