摘要： An improved fuel injection system is provided which incorporates a common rail and a plurality of unit injectors which function together to efficiently produce various injection rate shapes and different combinations of discreet and blended pilot, main, post and after treatment fuel injection events during a single injection. The fuel injection system effectively permits flexible, responsively timed, square shaped, discreet low to mid pressure level injections utilizing the fuel pressure of the common rail while also allowing the unit injector portion to function independently to produce flexible and responsively timed and pressure controlled, triangular shaped high pressure fuel injection events and to recover excess energy. In one embodiment, a separate common rail pump is avoided by utilizing the unit injector plunger to replace fuel into the common rail which was previously injected.

摘要： A hydraulically actuated dual fuel injector separately injects two fuels into a combustion chamber of an internal combustion engine. In particular, the two fuels may be controlled quantities of a first liquid fuel and a second gaseous fuel that are used to fuel a diesel engine. The injector preferably begins injecting the first fuel sequentially before beginning to inject the second fuel. The dual fuel injector comprises: (a) an injector body; (b) a hydraulic fluid inlet port formed in the injector body for enabling pressurized hydraulic fluid from a hydraulic fluid source to be introduced into the interior of the injector body, said hydraulic fluid being of sufficient pressure to maintain sealing and to prevent leakage of the gaseous fuel into the hydraulic fluid; (c) a first fuel inlet port formed in the injector body for enabling a first fuel to be introduced into the interior of the injector body; (d) a first injection valve disposed within the injector body fluidly connected to the first fuel inlet port for controlling injection of the first fuel from the injector through a first fuel ejection port; (e) a second inlet port formed in the injector body for enabling a second fuel to be introduced into the interior of the injector body; (f) a second injection valve disposed within the injector body fluidly connected to the second inlet port for controlling injection of the second fuel from the injector through a second fuel ejection port; (g) a first two-way control valve which controls the flow of the hydraulic fluid to actuate the first injection valve; (h) a second control valve which controls the flow of the hydraulic fluid to actuate the second injection valve; (i) a metering device within the injector body for metering the amount of first fuel injected by the first injection valve; and (j) a seal in the injector body which prevents leakage of the second fuel within the injector body.

摘要： An integrated fuel injector and ignitor assembly is provided which includes an injector body, a fuel control valve and an ignition device. The components are packaged to create a compact assembly for positioning within an injector mounting bore and particularly in a mounting bore of an existing diesel engine. The assembly may include a fuel reservoir for accumulating fuel for injection so as to stabilize the injection pressure. Also, the ignition device may include an ignition coil mounted on the injector body and a replaceable ignitor electrode cartridge mounted on an opposite end of the injector body to permit simple, cost effective replacement of the electrodes/spark plug.

摘要： A valve for selectively permitting the flow of fluid therethrough is disclosed including a housing having at least one inlet and at least one outlet, a valve seat provided in the housing about the inlet, a displaceable ball for cooperating with the valve seat for sealing fluidic communication between the inlet and outlet and a ball guide for guiding the ball between a closed position in contact with the valve seat and an open position spaced from the valve seat. The ball guide includes a central bore for reciprocally receiving the ball and a plurality of circumferentially spaced fluid passages in fluid communication with the inlet, the passages extending substantially parallel to a longitudinal extent of the central bore such that a flow of fluid through the inlet is directed radially outwardly from the central bore and into the circumferentially spaced passages when the ball is in the open position. Fluid flow through the valve seat is thus restricted to flow through a sharp right angle bend allowing more fluid momentum to be used to hold the ball in a stable position. Accordingly, a majority of the flow is directed underneath the ball and only a small amount of flow goes through the clearance between the ball and the central bore of the ball guide, such that the ball is maintained in a stable condition thus resulting in more consistent flow metering.
摘要翻译：公开了一种用于选择性地允许流体流过的阀，其包括具有至少一个入口和至少一个出口的壳体，围绕入口设置在壳体中的阀座，用于与阀座配合以用于密封流体连通的可移位球在入口和出口之间以及球引导件，用于在与阀座接触的关闭位置和与阀座间隔开的打开位置之间引导球。球引导件包括用于往复地接收球的中心孔和与入口流体连通的多个周向间隔开的流体通道，通道基本上平行于中心孔的纵向延伸，使得通过入口的流体流是当球处于打开位置时，从中心孔径向向外指向周向间隔开的通道。因此，通过阀座的流体流动被限制流过锋利的直角弯曲，允许更多的流体动量用于将球保持在稳定的位置。因此，大部分流动被引导到球的下方，并且只有少量的流动通过球和球导向件的中心孔之间的间隙，使得球保持在稳定状态，从而导致更一致流量测量。

摘要： A fluid control device for use in a high pressure fluid system, the device including a device body with a cavity and a high pressure circuit, a plunger positioned for reciprocal movement in the cavity, and a leakage reduction cap mounted to the plunger for reducing fluid leakage flow. In one implementation, the leakage reduction cap includes a flexible portion positioned between the device body and the plunger, and defining an annular clearance gap between the leakage reduction cap and the device body. The flexible portion of the leakage reduction cap resiliently flexes radially outwardly in response to fluid pressure forces to reduce the annular clearance gap so as to minimize fluid leakage flow through the annular clearance gap.
