Abstract (en)
[origin: FR2773851A1] The fuel injector has a body (10), containing a needle (12) terminated by an obturation part with a seat (28), for fuel passage. In the seat (28) is a diffusion hole (30). The needle (12) is displaceable between a first axial position, in which the obturation part presses against the seat (28), and a second position where the obturation part is clear of the seat (28). The injector also includes a chamber which rotates the fuel around the axis of the obturation part. The chamber is defined by the front face of the seat (28), by a disc (42) applied on the seat and having slots which tangentially open into a central opening surrounding the obturation part, and by a needle guide (40) arranged so that it feeds the external ends of the disc (42) slots. The disc (42) is pinched between the guide (40) pressing against an internal shoulder of the body (10) and the seat fixed to the body.
