Multi-point injector for turbomachine

摘要

The injector has two shells (34, 35) with bodies encased relative to each other such that internal openings and external diameters of the bodies mutually and partially overlap by defining a hollow volume. The volume comprises three concentric baffles (360-362) that are continuous and communicated with distinct controlled circulation channels. The baffles (361, 362) are opened into a fuel intake chamber (37) placed in a zone for supply of fuel and homogenous cooling of the injector, where the zone is diametrically opposite to the channels and communicated with a metering jet. An independent claim is also included for a method for manufacturing a multipoint type fuel injector.
