    摘要: A mobile valve member (48) designed to be arranged in the nozzle body (30) of a fuel (F) injector (10), extends along a main axis (XI) and comprises a piston (50) formed of a male first cylinder (62) of effective diameter (DE) forming the top end of the mobile member (48) and of a second cylinder (64) provided with an internal cylindrical bore (68) of diameter (DE) and a shutoff member (52) comprising a male cylindrical shaft (84) of effective diameter (DE) which is a sliding fit in the internal bore (68), and of a member (88) extending as far as a pointed end provided with a mobile seat (56) and forming the bottom end of the mobile member (48). The mobile member (48) is hydraulically balanced and has a length between its top end and its bottom end that is variable because of the sliding of the cylindrical shaft (84) in the internal bore (68) of the piston.

    摘要: A method of operating a solenoid actuator is described. The solenoid actuator comprises an armature, pole piece(s), electromagnet coil(s) arranged, in response to energisation, to cause travel of the armature between first and second positions along a direction of travel. The method comprises applying, in a cycle, drive waveform(s) to the electromagnet coil(s), the drive waveform(s) including turn-on drive waveform(s) having profile(s) and duration so as to position the armature at a position between the first and second positions and at which the armature is substantially at rest, obtaining measurement(s) of back emf and/or current and/or resistance from the electromagnet coil(s) and adjusting the drive waveform(s) applied to the electromagnetic coil in the cycle and/or adjusting drive waveforms(s) applied to the electromagnetic coil in a subsequent cycle using the measurement(s).
