Abstract (en)
[origin: EP2040001A2] The chamber has an external wall and internal wall connected by a truncated conical shaped bottom wall (16) forming a bottom of the chamber. The wall is pierced with orifices (16s) for a fuel injection system. Deflectors are centered on each of the orifices and include a flat shoulder by which the deflectors are supported against a portion of a flat surface along a circumference of the orifices. The wall is constituted of flat surfaces (16f) surrounding each of the orifices. The shoulder is supported against a flat surface of the facets.
