摘要： In one aspect, a fuel injector includes an injector body that defines a fuel inlet, a drain outlet and a nozzle outlet. A direct operated check valve is positioned in the injector body and includes a needle valve member with an opening hydraulic surface exposed to fluid pressure in a nozzle supply passage, and a closing hydraulic surface exposed to fluid pressure in a needle control chamber. The needle valve member is movable between a first position at which the nozzle supply passage is blocked to the nozzle outlet, and a second position at which the nozzle supply passage is open to the nozzle outlet. A needle control valve is positioned in the injector body and includes a control valve member movable between a first position at which the needle control chamber is fluidly connected to the drain outlet, and a second position at which the needle control chamber is fluidly blocked to the drain outlet. A solenoid actuator is positioned in the injector body and includes a stator assembly and an armature assembly coupled to the control valve member. One of the stator assembly and the armature assembly includes a non-magnetic insert that moves into and out of contact with another of the stator assembly and the armature assembly at an energized position and a de-energized position, respectively.

摘要： A common rail single fluid injection system including fuel injectors with the ability to produce multiple injection rate shapes. This is accomplished by including auxiliary filling orifices which selectively provide pressurized fluid to the check needle control chamber during injection events. In so doing, the speed and movement of the check needle is manipulated and differing injection rates may be achieved.

摘要： A common rail fuel injector includes a needle valve member that moves to open and close nozzle outlets for a fuel injection event responsive to pressure in a needle control chamber. Between injection events, the needle control chamber is fluidly connected to the fuel inlet by a first pathway that includes a Z orifice, and fluidly connected to the fuel inlet by a second pathway that includes an F orifice, an intermediate chamber and an A orifice. During an injection event, the needle control chamber is fluidly connected to a drain outlet by a third pathway that includes the A orifice, the intermediate chamber and an E orifice. Different performance characteristics are achieved by adjusting the sizes of the respective of F, A, Z and E orifices.

摘要： The present disclosure relates to settler plates for a plate settler. The settler plates generally include a hollow support with a hollow interior to receive clarified liquid from a flow channel between adjacent settler plates. An orifice is formed through the hollow support to direct clarified liquid from the flow channel into the hollow interior. The orifice can be positioned such that clarified liquid can flow upwardly out of the flow channel and downwardly through the orifice into the hollow interior. The hollow support can be integrally formed with the settler plate. For example, the hollow support can be formed by bending a tab extending from an end of the settler plate. The tab can be bent into a hollow support with a cross section that is generally polygonal.

摘要： A fuel injector for an engine is disclosed. The fuel injector may have a fuel nozzle with at least one injection orifice, and a needle element movable within the fuel nozzle between a first position at which the needle element inhibits fuel flow and a second position at which fuel flow is substantially uninhibited. The fuel injector may also have a control chamber located at a base end of the needle element, a body, and a control valve disposed within the body and movable to selectively drain the control chamber, thereby causing the needle element to move between the first and second positions. The fuel injector may further have an armature disposed within an armature cavity of the body and selectively energized to move the control valve, and a pressure reducer disposed within the body and configured to reduce a pressure of the armature cavity.

摘要： A low leakage large bore fuel system includes a common rail fluidly connected to at least one of a source of heavy fuel oil and a source of distillate diesel fuel. A plurality of fuel injectors are fluidly connected to the common rail and each include a cooling inlet and a cooling outlet. Each fuel injector also includes an electrical actuator coupled to a direct operated nozzle check valve by a pilot valve member and a control valve member. Fuel leakage is reduced between injection events by equalizing pressures in a pilot control chamber and an intermediate control chamber that are separated by a guide surface of the control valve member. Also, between injection events the pilot valve member blocks a drain outlet from a common rail inlet of the fuel injector.

摘要： A valve assembly including an armature and a valve member that are coupled when the solenoid coil is de-energized but are decoupled after the solenoid coil is energized. A first spring biases the armature and the valve member to a closed valve seat position while a second spring having a smaller preload than the first spring biases the valve member to an open valve seat position. When the solenoid coil is energized, the magnetic force of the coil overcomes the force exerted by the first spring pulling the armature away from the valve member. The valve member moves to the open valve seat position by the force exerted by the second spring. When the coil is de-energized, the magnetic force decays, thereby allowing the armature and the valve member to re-couple.

摘要： Apparatus and method for controlling the positioning of substrates for supporting bacteria in a waste treatment container use an aerator manifold which supplies bubbles of gas to the container from adjacent the bottom of the container. A hollow open mesh tube forms the substrate and is extended under the manifold to define a leg extending upwardly from each side of the manifold. A buoyant array piece is secured to each such end and urges the tube upwardly toward the upper surface of the waste. The bubbles establish a rolling upward flow of the waste in the container between the legs of the tube, which urges the buoyant array pieces apart both during the treatment operation and during draining of the container. Such urging during draining urges the buoyant array pieces away from the manifold, which pieces carry the ends of the tube away from the manifold as they become located lower in the basin. Such urging avoids tangling of the tubes with the manifold and facilitates more efficient cleaning of the manifold. Units of the array pieces are formed by clipping the array pieces together in various configurations, which additionally assists in keeping the array pieces and tubes away from the manifold.
摘要翻译： 用于控制用于在废物处理容器中支撑细菌的基底的定位的装置和方法使用曝气器歧管，所述曝气器歧管从邻近容器的底部向容器提供气体气泡。 中空的开口网管形成基底并在歧管下方延伸以限定从歧管的每一侧向上延伸的腿部。 一个漂浮的阵列件被固定到每个这样的端部并且将管向上推向废物的上表面。 气泡在管的腿之间的容器中形成向上滚动的浪费，其在处理操作期间和在排出容器期间促使浮力排列件分开。 在排水期间的这种推动促使浮力的排列件远离歧管，当它们位于盆中较低的位置时，这些件将管的端部远离歧管。 这种推动避免了管与歧管的缠结，并且有助于更有效地清洁歧管。 阵列片的单位是通过以各种配置将阵列片夹在一起形成的，这另外有助于保持阵列片和管远离歧管。
