Abstract

The invention relates to a mixing device for mixing combustion air and gas for a gas appliance, having a housing (2) with a gas supply connected thereto, and having a nozzle insert (4) which is arranged in the housing (2) and which has a predetermined throughflow cross-sectional area (Q). The housing (2) has an inlet region (6) forming an inlet portion (7), which narrows in the flow direction, of a venturi nozzle (3), wherein the nozzle insert (4) forms at least one outlet portion (13), which widens in the flow direction, of the venturi nozzle (3).
