    摘要： The invention relates to an injector comprising a nozzle that includes an opening and a seat, a needle movably mounted in the nozzle and having an end defining a valve in a contact area with the seat, a means for vibrating the valve, a first acoustic-impedance breaking area at a first distance from the valve along the nozzle, and another first acoustic-impedance breaking area at a second distance from the valve along the needle. According to the invention, each of the first and second distances is such that the respective propagation time of acoustic waves along said distance is: Ti = ni *[ζ/2], where r\\ is a positive integer coefficient different from zero with i = 3 for the first distance and i = 4 for the second distance, ζ being a period of the vibrations.

    摘要： The invention concerns a fuel injection device for internal combustion engine. The fuel injection device for internal combustion engine comprises an injecting head integral with the end of a needle (3) mobile in translation inside an injection housing (4) supplied with high pressure fuel and having a seat for the injecting head, and a piezoelectric or magnetoresistive vibratory element (5) capable, when it is energized, to act on the needle (3), maintained by a return spring (10), to cause same to vibrate, such that the injecting head co-operates with its seat to periodically open and close a passage for fuel injection. The device comprises means for controlling (16, 17) the movement of the needle in translation, countering the return spring (10), independent of the vibratory element (5).

    摘要： The invention relates to a fuel nozzle comprising a nozzle body (10), a pintle (12) slidably mounted in a bore (14) of the nozzle body (10), and first restrictor means (16) for restricting the flow of fuel delivered by the nozzle to a first flow rate (18). In order to achieve a wider range of the flow rate, one or more second restrictor means (20) for restricting the flow of fuel delivered by the nozzle to a second flow rate (22) differing from the first flow rate are provided according to the invention.
