    • The present invention provides a fuel injector, comprising a housing having a scalable injector seat; a fuel injector pin disposed within the housing proximate to the injector seat such that the injector seat may be sealed and unsealed by displacing the fuel injector pin; a resilient element biasing the fuel injector pin in an unsealed direction; a piezoelectric actuator disposed within the housing proximal to the fuel injector pin configured to actuate to force the injector pin towards the injector seat to seal the injector seat; and a thermal compensating unit disposed within the housing proximal to the actuator and configured to compensate for thermal expansion or contraction of a component of the fuel injector.
    • 本发明提供一种燃料喷射器,包括具有可伸缩的喷射器座的壳体; 燃料喷射器销,其设置在靠近所述喷射器座的所述壳体内,使得所述喷射器座可以通过移动所述燃料喷射器销而被密封和未密封; 一个弹性元件,沿着未密封的方向偏置燃料喷射器销; 压电致动器,其设置在所述壳体的靠近所述燃料喷射器销的所述壳体中,所述压电致动器构造成致动以迫使所述喷射器销朝向所述喷射器座以密封所 以及热补偿单元,其设置在所述壳体内靠近所述致动器并且被配置为补偿所述燃料喷射器的部件的热膨胀或收缩。
