    • Direct needle control fuel injectors and methods disclosed. The preferred embodiment injectors have a needle within a needle chamber for movement between a closed position preventing injection of fuel and an open position allowing injection of fuel, a source of high pressure fuel coupled to the needle chamber to provide fuel for injection and to hydraulically urge the needle to the open position by pressurizing a first hydraulic area associated with the needle, a needle control hydraulic area having a second hydraulic area disposed to urge the needle to the closed position when the second hydraulic area is exposed to fuel under pressure, and valving coupled to the source of high pressure fuel and a vent to controllably couple the hydraulic area of the needle control member to the high pressure fuel or to the vent.
    • 直接针控燃油喷射器和方法披露。 优选实施例注射器具有在针室内的针,用于在阻止燃料喷射的关闭位置和允许喷射燃料的打开位置之间移动,打开位置允许喷射燃料,耦合到针室的高压燃料源以提供喷射燃料并液压地推动 所述针头通过对与所述针头相关联的第一液压区域进行加压而进入打开位置;针控制液压区域,具有第二液压区域,所述第二液压区域设置成当所述第二液压区域在压力下暴露于燃料时将所述针推向所述关闭位置, 耦合到高压燃料源和通气口,以可控地将针控制构件的液压区域耦合到高压燃料或通气孔。
