摘要： Steel rod stock is shaped into a fuel injector tip having a central axis and including a shank extending between a mating end and a nozzle end. An inner surface of the fuel injector tip includes a conical needle valve seat and defines a nozzle chamber and a sac on opposite sides of the needle valve seat. The mating end includes a injector stack surface and an injector body contact surface. After shaping the fuel injector tip, it is a case hardened to a hardness in excess of HRC 55. Next, the nozzle end is shaped, after the case hardening step, to include a plurality of nozzle surfaces that each define one of a plurality of nozzle outlets extending between the sac and the outer surface. The inner surface and the nozzle surfaces are then autofrettaged to induce compressive residual stress at the case hardened needle valve seat, the case hardened sac and at least a portion of the nozzle surfaces closest to the sac.

摘要： A hydraulic system, such as a fuel injection system, includes a fixed displacement pump with at least one pump piston. A sleeve surrounds each pump piston and provides the method by which fluid displaced by the pumping stroke of the pump piston is directed either to a high pressure area in the pump or a low pressure area. The sleeves are a portion of an electro-hydraulic controller that includes a mechanical bias to bias the pump to a high output position when a pressure differential between the outlet area and the inlet area is relatively low, such as at cold start up. This aspect facilitates priming of the system. In addition, the controller includes a biasing hydraulic surface in opposition to the mechanical biaser that serves to bias the pump to its low output position when the pressure differential between the outlet area and the inlet area is relatively high. This aspect prevents over pressurization in the event that electric current to the controller is disrupted.

摘要： A hydraulically-actuated system includes a fix displacement variable delivery pump with a plurality of parallel disposed pistons that reciprocate in a pump housing the defines a high pressure portion and a low pressure area. A control device is attached to the pump housing and moveable between a first position in which the pistons displace fluid into the high pressure portion and a second position in which pistons spill fluid back to the low pressure area. The control device includes an electrically driven linear motion device, a linkage and a plurality of sleeves, one being disposed on each piston. Linear movement of the control device in turn causes linear movement of the sleeves. The position of the sleeves in turn determines the amount of output of the pump.

摘要： In one case of hydraulically actuated fuel injection systems, the engine lubricating oil is utilized as the hydraulic medium to actuate the individual fuel injectors. In a typical example, these fuel injectors are fluidly connected to a common rail that is maintained a relatively high pressure when the engine is running. When the engine is turned off, the oil in the common rail both drops in pressure and in temperature. As this occurs, a thermal contraction effect takes place. This lost volume is made up by an oil replenishing reservoir that captures some of the engine lubricating oil that finds its way into the chamber defined by the engine head and valve cover. A check valve is positioned between the oil replenishing reservoir and the common rail so that the two are isolated from one another while the engine is running. At free start, shorter engine cranking times are encountered because the hydraulically actuated fuel injection system can come up to full pressure substantially faster.
摘要翻译：在液压致动燃料喷射系统的一种情况下，发动机润滑油被用作液压介质以驱动各个燃料喷射器。在典型的例子中，这些燃料喷射器流体连接到在发动机运行时保持相对较高压力的共轨。当发动机关闭时，共轨中的油都会在压力和温度下都下降。发生这种情况时，会发生热收缩效应。这个丢失的体积由一个油补充储存器构成，该油储存器捕获一些发动机润滑油，该发动机润滑油进入由发动机头和阀盖限定的室中。止回阀位于油补充储存器和共轨之间，使得两个在发动机运行时彼此隔离。在自由起动时，遇到更短的发动机起动时间，因为液压致动的燃油喷射系统可以显着加快到达全压力。

摘要： A hydraulically-actuated system includes a fixed displacement pump with at least one piston that reciprocates in a pump housing that defines a high pressure area and a low pressure area. A control valve is attached to the pump housing and moveable between a first position in which the piston displaces fluid in a first proportion between the high pressure area and the low pressure area, and a second position in which the piston displaces fluid in a second proportion between the high pressure area and the low pressure area. At least one hydraulically-actuated device is connected to the high pressure area of the pump. A source of low pressure fluid is connected to the low pressure area of the pump. An electronic control module is in communication with and capable of controlling the position of the control valve.
