摘要： A hydraulically actuated fuel injector includes an injector body having a needle control chamber, a nozzle chamber, and a nozzle outlet that opens to the nozzle chamber. Fuel within the injector is hydraulically pressurized during each injection cycle. A needle valve is positioned to reciprocate in the nozzle chamber between an open position in which the nozzle outlet is open and a closed position in which the nozzle outlet is closed. The needle valve includes a closing hydraulic surface exposed to pressure in the needle control chamber. A needle control valve is mounted within the injector body and is moveable between an off position in which the needle control chamber is opened to a source of high pressure fluid and an on position in which the needle control chamber is opened to a low pressure passage.

摘要： A fuel injector assembly for a fuel injection system has a fuel pumping assembly with a fuel inlet and a fuel nozzle for causing fuel to be periodically pumped from the fuel inlet through the nozzle. The fuel injector assembly has an electro-hydraulic control valve associated with the fuel pumping means. The control valve comprises a housing, a first conduit formed in the housing and fluidly coupled to the fuel pumping means, a second conduit formed in the housing and fluidly coupled to a source of pressurized hydraulic fluid. A valve element is disposed in the housing and is reciprocable between a first position in which the first conduit is fluidly coupled to the second conduit and a second position in which the first conduit is fluidly isolated from the second conduit. The control valve also includes a pair of electrically energizable electromagnetic devices for controlling the reciprocation of the valve element. The components of the control valve are preferably composed of SAE 52100 steel so that the valve element remains latched in the first and second positions after electric current to the electromagnetic devices is turned off.

摘要： An improved electronically-controlled fluid injector system comprises a fluid storage chamber and a direct-operated check. Pressurization of fluid in the storage chamber begins before the start of fluid injection. Fluid injection begins by hydraulically unbalancing the check. Fluid injection sharply ends by hydraulically balancing the check to allow a biasing device to close the check. The present invention provides improved control of several fluid injection parameters, including higher peak fluid injection capability and less fluid injection pressure drop at the end of injection, resulting in improved engine performance and lower emissions, noise, and wear.

摘要： A variable delivery liquid pump system includes a housing defining an inlet, an outlet and a plunger bore. A rotating shaft includes a cam that defines a fixed displacement distance with each rotation of the shaft. A plunger is slidably positioned in the plunger bore. A supply of liquid at a supply pressure is attached to the inlet by a supply passage. An output control mechanism includes an electronically-controlled flow restriction valve positioned in the supply passage. The plunger retracts less than the fixed displacement distance of the cam during each rotation of the shaft when the flow restriction valve is at least partially closed. The variable delivery pump is particularly suited for use in a hydraulically-actuated fuel injection system.

Pressurization of fluid in the storage chamber begins before the start of fluid injection. Fluid injection begins by hydraulically unbalancing the check. Fluid injection sharply ends by hydraulically balancing the check to allow a biasing device to close the check. A fluid, such as fuel, can be injected as a purely vapor phase to improve mixing with combustion air.The present invention provides improved control of several fluid injection parameters, including higher peak fluid injection capability and less fluid injection pressure drop at the end of injection, resulting in improved engine performance and lower emissions, noise, and wear.

摘要： A rotor balancing arrangement is provided for use in a distribution valve to ensure hydrostatic balancing of a rotor located in the distribution valve. Some balancing arrangements provide areas equally spaced around the peripheral surface, each being exposed to the same pressure, however, they are limited to valves which rotate only through a limited arc of rotation. Other valves which rotate provide balancing grooves around portions of the peripheral surface but do not provide any control for the pressure that migrates axially in both directions along the peripheral surface of the rotor. In the subject arrangement, pressure fields of a predetermined size are located on a peripheral surface of a rotor circumscribing first and second outlet ports which open to opposite sides of the rotor. The size of the pressure fields is determined by the relationship of the diametrical clearance between the rotor and a bore with respect to the operating pressure of the system. This arrangement ensures that the differential forces acting on opposite sides of the rotor are minimized thus eliminating rotor sticking.
摘要翻译：提供了用于分配阀中的转子平衡装置，以确保位于分配阀中的转子的静水平衡。一些平衡装置提供围绕周边表面等间隔的区域，每个区域暴露在相同的压力下，然而，它们仅限于仅通过有限的旋转旋转旋转的阀。旋转的其它阀提供围绕周边表面的部分的平衡槽，但是不对沿着转子的外周表面沿两个方向轴向移动的压力提供任何控制。在主题布置中，预定尺寸的压力场位于限定转子相对侧的第一和第二出口的转子的外周表面上。压力场的尺寸由转子和孔之间的直径间隙相对于系统的操作压力的关系确定。这种布置确保了作用在转子相对侧上的差动力最小化从而消除了转子的粘附。
