Abstract:
A venturi nozzle ( 1 ), disposed upstream from a blower ( 20 ), for mixing combustion air and fuel gas by intake pressure of the blower ( 20 ), comprising: a nozzle portion ( 12 ) with a shape that is narrowed in diameter downstream and into which combustion air is introduced; a mixing portion ( 13 ), disposed downstream from the nozzle portion ( 12 ), with a shape that is enlarged in diameter downstream and into which combustion air and fuel gas are mixed; and a fuel gas inlet ( 15 ), disposed between the nozzle portion ( 12 ) and the mixing portion ( 13 ), into which fuel gas is introduced; wherein a plurality of ridges ( 16 ) extending in a circumferential direction and arranged at predetermined intervals in a flow direction of combustion air are formed on an inner surface of the nozzle portion ( 12 ).

Claim (Index 4):
The venturi nozzle according to  claim 1 , wherein,\n among surfaces constituting the ridges, surfaces faced to a central axis side extend parallel to a central axis or perpendicular to the central axis, or diverge from the central axis in an upstream direction, and wherein, among surfaces constituting the ridges, surfaces faced to an outer surface side of the nozzle portion extend parallel to the central axis or perpendicular to the central axis, or approach to the central axis in the upstream direction.
