The injector comprises a single control winding (3) and two parallel cores (5,6), with an armature (4), each core defining one of two magnetic air gaps (7,8) which are parallel and variable. The first core (5) is pressed against its spring (10) so that its shutter (13) exposes a calibrated hole (15) when there is a first level of current in the winding. The second core (6) is pressed against its spring (16) so that its shutter (18) exposes the second calibrated hole (19) when the winding is supplied with current at a higher level than the first current level. <IMAGE> |
