Abstract:
A device for sucking a gas or a gas mixture and for mixing it with a liquid fuel flowing in a flow duct provided with walls, the device comprising:a liquid intake duct and outlet duct, which have first flow cross-sectional areas; a throttle section between the intake and outlet ducts comprising at least one elongate throttle duct for the flowing liquid fuel; and at least one gas duct transverse to a center line of the throttle duct, which gas duct opens as a gas supply orifice into the throttle duct, said throttle duct forming for the flow a second flow cross-sectional area, which is substantially smaller than said first flow cross-sectional areas, and extending with a substantially unchanging flow cross-sectional area from the point of said gas supply orifice to a downstream length on the downstream side of the liquid flow, wherein the throttle section further comprises as a combination: a second one-way valve in the outlet duct arranged to open with a second pressure value; and said at least one gas duct opens as a gas supply orifice/gas supply orifices into the throttle duct at least substantially on a first side of a plane running through the center line of the throttle duct, and continues as a connecting duct outside the throttle duct to the opposite side of said plane and further to the gas mixture/gas source.
