    • An anti-coking bushing assembly for sealing a pintle shaft of an EGR control valve, comprising a bushing carrier disposed in the valve body and supportive of close-fitting pintle shaft bushing liners formed of a polyimide such as Vespel. The bushing carrier and bushing liners are installed into a carbon shield extending into the exhaust flow space within the valve. Within the carbon shield, between the gas flow space and the bushing carrier, is a ring seal on the pintle shaft and a gas expansion chamber to cool exhaust gas escaping along the pintle shaft, allowing contaminants in the exhaust gas to precipitate in the gas expansion chamber. The carbon shield, ring seal, bushing carrier, and bushing liners are conveniently pre-assembled as an anti-coking bushing assembly for subsequent installation into a valve body during final valve assembly.

    • A dual-coil outwardly-opening fuel injector including a fuel tube connected at a lower end to a lower injector housing. Within the fuel tube are a lower (opening) solenoid pole piece, a specially-formed armature, and an upper (closing) solenoid pole piece. A seat assembly including an injector nozzle, swirler, and valve seat are adjustably threaded into the lower housing. A pintle assembly, including a solid pintle portion supporting a valve head and a tubular portion welded thereto, is axially disposed within the fuel tube and is welded to the armature which is spaced from the lower pole piece by a distance equal to the opening stroke of the valve. A return spring adjustment mechanism disposed on the upper pole piece engages the upper end of the pintle assembly for varying the closing force of the return spring. Opening and closing solenoid preassemblies are mounted external to the fuel tube for magnetically engaging the pole pieces and armature within in known fashion.

    • A dual-poppet valve comprising a valve body having spaced-apart coaxial valve seats and being arranged such that first and second poppets both open into the primary chamber. A first pintle shaft engages the first poppet, and a second pintle shaft engages the second poppet. A motorized actuator having a gear transmission includes a pinion gear. The pintle shafts include opposing gear racks, and the pinion gear engages both racks. Thus, rotation of the pinion gear in a first direction causes both poppets to be lifted from their seats simultaneously, in opposite directions; and counter-rotation engages each poppet with its respective seat. In closing, one poppet engages its seat slightly before the other poppet engages the other seat. The first pintle slides through the first poppet until the second poppet is fully seated by the actuator. The force of the spring fully engages the first poppet with the first seat.
    • 一种双提升阀,包括具有间隔开的同轴阀座的阀体,并且布置成使得第一和第二弹簧都打开进入主室。 第一枢转轴接合第一提升阀,第二枢轴接合第二提升阀。 具有齿轮传动装置的电动执行器包括小齿轮。 枢轴包括相对的齿条,小齿轮啮合两个齿条。 因此,小齿轮在第一方向上的旋转使得两个弹簧都能沿相反的方向同时从其座上升起; 并且反向旋转使每个提升阀与其相应的座椅接合。 最后,一个提升阀略微靠在另一个提升阀接合另一个座位之前。 第一枢轴滑过第一提升阀,直到第二提升阀被执行器完全固定。 弹簧的力完全与第一座椅接合。

    • A bearing module for a pintle valve including a pintle bearing, bearing spring, and two-part housing. The bearing has an axial face for sealing against an inner axial surface of the housing. The bearing diameter is less than the diameter of the housing, permitting the bearing to float radially. The housing fits into a port in the valve body and also extends over an axial surface of the body, thus forming a seal against the wall of the port and the surface of the body. The bearing spring, preferably a wave washer, is compressed within the housing as the two housing parts are assembled to form the module. In a currently preferred embodiment, the housing further comprises a coking shield extending along the surface of the pintle shaft within the valve port to reduce the tendency for coking gases to enter the bearing module.
    • 一种用于枢轴阀的轴承模块,其包括枢轴轴承,轴承弹簧和两部分壳体。 轴承具有用于密封壳体的内轴向表面的轴向面。 轴承直径小于外壳的直径,允许轴承径向浮动。 壳体装配在阀体中的端口中并且还延伸到主体的轴向表面上,从而形成抵靠端口的壁和主体的表面的密封。 当组装两个壳体部件以形成模块时,轴承弹簧,优选地是波形垫圈,在壳体内被压缩。 在目前优选的实施例中,壳体还包括沿着阀口内的枢轴的表面延伸的焦化屏蔽,以减少焦化气体进入轴承模块的趋势。
