A nozzle for a fuel injector, in particular for a gas-turbine engine, is provided comprising a planar conductive electrode (104) with a sharp edge forming an aperture; an upper insulation layer (102) above the electrode and a lower insulation layer (106) below the electrode, both insulation layers having apertures; and a swirler arrangement (112) for creating a swirling action in liquid fuel introduced into the nozzle. The axis of swirl is generally perpendicular to the plane of the electrode. In use the swirling fuel passes through the aperture of the lower insulation layer, the aperture of the conductive electrode and the aperture of the upper insulation layer. As the fuel passes through the aperture of the electrode, the electrode charges the swirling fuel, so that the nozzle supplies charged droplets of atomised fuel from an outlet orifice. The swirler arrangement may be a radial or axial swirler arrangement. |
