Abstract (en)
[origin: EP2218905A1] An injector comprises a closing element (7) comprising a conical flow guiding surface (15) and a deflection element (16) arranged at the flow guiding surface (15) of the closing element (7). The deflection element (16) is dimensioned to deflect a fluid flow only during a first time period directly following a beginning of each opening phase of the injector during which the fluid flow is guided by the flow guiding surface (15) of the closing element (7) from a first flow direction (FD1) upstream the deflection element (16) to a second flow direction (FD2) differing from the first flow direction (FD1) such that the fluid is injected in the second flow direction (FD2). The injector further comprises a cartridge (4) with a flow guiding surface (11). The flow guiding surface (11) of the cartridge (4) is arranged for taking over a guidance of the fluid flow from the flow guiding surface (15) of the closing element (7) during a second time period directly following the first time period such that the fluid is injected in a third flow direction differing from the second flow direction (FD2).
