Patent ID: 7780151

Claim:
A mixer assembly for forming a fuel-air mixture, which is useful with a burner system of a heat engine, comprising: a flow-through component including at least one air inlet opening, at least one flow outlet opening, a flow passage which connects the air inlet opening to the flow outlet opening, and at least one fuel feed located in the region of the at least one air inlet opening, along the flow passage, or both; wherein the flow-through component further comprises a flow deflecting region which includes at least two of said air inlet openings and a flow passage section for and in fluid communication with each air inlet opening, which flow deflecting region is configured and arranged to deflect an air flow which enters the respective flow passage section by a deflection angle β≠0°, the flow passage sections including an outlet opening for each flow passage section, wherein the flow passage sections are configured and arranged for isokinetic flow-through ratios, wherein β is the angle between an inflow direction of air into the at least two air inlet openings and an outflow direction of the outlet opening of the flow passage section; and (a) a mixing passage section connected to each of the outlet openings of the flow passage sections, at least one flow vortex generating structure positioned in each mixing passage section, and each mixing passage section including an outlet opening; or (b) a fine mixing region connected to the outlet openings of the flow passage sections, which fine mixing region includes a multiplicity of individual flow passages which each have a passage cross section dimensioned smaller than the passage cross section of the flow passage sections in the region of the outlet openings of the flow passage sections; or (c) a mixing passage section connected to each of the outlet openings of the flow passage sections, at least one flow vortex generating structure positioned in each mixing passage section, each mixing passage section including an outlet opening, a fine mixing region having a multiplicity of individual flow passages connected to each mixing passage section outlet opening, the individual flow passages each having a passage cross section dimensioned smaller than the passage cross section of the mixing passage sections in the region of their outlet openings.
