Fuel injector assembly for turbine engines

A turbine engine comprising:

• a compressor section and a combustor section, wherein the combustor section comprises:
• a fuel injector fuel injector nozzle assembly comprising:
• an inner housing body having a center body installed within the inner housing, the center body defining a nozzle axis;
• an intermediate housing body arranged radially outward from the inner housing;
• an outer housing body arranged radially outward from the intermediate housing;
• and
• a float swirler arranged radially outward from the outer housing body;
• wherein:
• the center body is a hollow body structure;
• a first fluid passage partially defined between an outer surface of the inner housing and an inner surface of the intermediate housing is configured to supply a first fluid;
• a second fluid passage partially defined between the intermediate housing and the outer housing is configured to supply a second fluid, the second fluid passage comprising at least one vane arranged to impart a swirl to a fluid passing through the second fluid passage and an accelerating passage defined downstream from the at least one vane and configured to accelerate the fluid passing through the second fluid passage;
• and
• a plurality of third fluid passages are configured to supply a third fluid, the plurality of third fluid passages comprising:
• a center third fluid passage defined within the center body,
• an inner third fluid passage defined within the float swirler between an external surface of the outer housing body and an inner surface of an inner swirler body, and
• an outer third fluid passage defined within the float swirler and radially outward from the inner third fluid passage between an exterior surface of the inner swirler body and an inner surface of an outer swirler body.
