    • An ultrasonic liquid delivery device in which a housing of the device has an internal chamber and at least one exhaust port in fluid communication with the internal chamber of the housing. A valve member is moveable relative to the housing between a closed position in which liquid is inhibited against exhaustion from the housing via the at least one exhaust port, and an open position in which liquid is exhaustable from the housing via the at least one exhaust port. An ultrasonic waveguide separate from the housing and valve member is disposed at least in part within the internal chamber of the housing to ultrasonically energize liquid within the internal chamber prior to liquid being exhausted from the housing in the open position of the valve member. An excitation device is operable in the open position of the valve member to ultrasonically excite the ultrasonic waveguide.
    • 一种超声波液体输送装置,其中所述装置的壳体具有内部腔室和与所述壳体的内部腔室流体连通的至少一个排气口。 阀构件可在相对于壳体移动的关闭位置之间移动,在该关闭位置中液体经由至少一个排气口被禁止从壳体排出,以及打开位置,在该位置,液体可经由至少一个排气口从壳体排出 。 与壳体和阀构件分离的超声波波纹管至少部分地设置在壳体的内部腔室内,以在液体从阀壳体在阀构件的打开位置排出之前对内部腔室内的液体进行超声波激励。 励磁装置在阀构件的打开位置可操作以超声波激发超声波导。

    • PURPOSE: A fuel injection valve is provided to contain a pump piston being possibly driven for operating a translational pump movement by a piezo-electric or a magnetostrictive actuator. CONSTITUTION: The invention relates to a fuel injection valve, specially a fuel injection valve for fuel injection systems in internal combustion engines. The inventive device has a pump piston (7) which is driven by a piezo-electric or magnetostrictive actuator (2) to create translational pump movement. An injector nozzle (70) with at least one injection opening (7) is hydraulically connected to the pump piston by a fuel pressure line (60). The fuel injector nozzle (70) opens when the fuel pressure produced by the pump piston(7) in the fuel pressure line (60) exceeds a given threshold value. At least one non-return valve (61) opening in the direction of the injector nozzle (70) and closing in the opposite direction is arranged in the fuel pressure line (60).
    • 目的:提供燃料喷射阀以容纳泵活塞,该泵活塞可能被驱动以通过压电或磁致伸缩致动器来操作平移泵运动。 构成:本发明涉及一种燃料喷射阀,特别是用于内燃机燃料喷射系统的燃料喷射阀。 本发明的装置具有由压电或磁致伸缩致动器(2)驱动以产生平移泵运动的泵活塞(7)。 具有至少一个喷射开口(7)的喷射器喷嘴(70)通过燃料压力管线(60)与泵活塞液压连接。 当燃料压力管线(60)中由泵活塞(7)产生的燃料压力超过给定阈值时,燃料喷射器喷嘴(70)打开。 至少一个在喷射器喷嘴(70)的方向上开口并在相反方向上关闭的止回阀(61)设置在燃料压力管线(60)中。

    • 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: T= n*[P/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, P being a period of the vibrations.
