摘要： According to the present invention, a fuel injection apparatus includes a casing having a control pressure chamber for storing fuel supplied from fuel passage, a needle valve to which fuel stored in the control pressure chamber applies pressure in the valve closing direction, a valve device for interrupting communication between the fuel passage and the control pressure chamber to seal fuel in said control pressure chamber, and volume changing device for expanding volume of the control pressure chamber after fuel is sealed in the control pressure chamber by the valve device. According to the above fuel injection device, pressure in the control pressure chamber is reduced while the fuel is stored therein by the volume changing device, the nozzle needle is lifted, and injection is started. For this reason, it is not necessary to supply surplus fuel in addition to the injection fuel during the fuel injection. In this way, the fuel supply pump is made smaller in size, and efficiency for use of supplied fuel can be improved. Further, since high-pressure fuel is not discharged from the fuel injection apparatus, pulsation within the common rail can be suppressed, and fuel injection can be stabilized.
摘要翻译：根据本发明，燃料喷射装置包括壳体，其具有用于存储从燃料通路供给的燃料的控制压力室，控制压力室中储存的燃料向其中关闭方向施加压力的针阀，中断燃料通道和控制压力室之间的连通以密封所述控制压力室中的燃料;以及容积改变装置，用于在燃料通过阀装置密封在控制压力室中后扩大控制压力室的容积。根据上述燃料喷射装置，通过容积变更装置将燃料储存在控制压力室内的压力降低，喷嘴针被提起，喷射开始。因此，在燃料喷射期间除了喷射燃料之外，不需要提供多余的燃料。以这种方式，使燃料供给泵的尺寸更小，并且可以提高供给燃料的使用效率。此外，由于高压燃料不从燃料喷射装置排出，所以能够抑制共轨内的脉动，能够稳定燃料喷射。

摘要： To provide a fuel injection pump which can sufficiently and stably supply fuel to a fuel pressurization chamber during a fuel intake stroke, a plunger chamber, a spill port and a spill passage are mutually communicable, while a reflux passage, an intake gallery, an intake passage, an intake port and the plunger chamber are mutually communicable. A reflux passage communicates with a damping chamber through a communication passage. The spill passage and the reflux passage communicate with each other, and when a spill valve opens, high-pressure fuel within the plunger chamber spills from the spill valve and into the intake gallery through the reflux passage, causing pulsation having a pressure level difference to the spill fuel. When the pulsation wave passes through the damping chamber, as the level difference in the pulsation wave is reduced, a sufficient quantity of fuel can stably be supplied from the intake gallery to the plunger chamber.

摘要： An electromagnetic fuel injection valve includes a needle valve having a sealed bore of a specified length formed therein a guide hole within which the needle valve is movable. A stopper plate and a valve seat portion ar provided for defining opened and closed positions of the needle valve. Further, a magnetic powder of a specified mass is movably received in the bore. When the needle valve collides with the stopper plate or the valve seat portion, the magnetic powder is moved by an inertia force acting. Due to collision of the magnetic powder with an end of the bore with a specified time lag, a bouncing force resulting from the collision of the needle valve can be canceled. Accordingly, a bounce of the needle valve can be restrained. further, since the inertia force acting on the magnetic powder is utilized, the durability can be improved as compared with the prior art.

摘要： A fuel injection valve of a diesel engine, comprising a valve body including a concave conical surface in the tip portion of the valve body, and fuel injection holes extending from the concave surface to the outside of the valve body, and a needle valve movable in the valve body and including a cylindrical shaft portion, a first conical surface adjacent to the shaft portion and having a conical angle smaller than that of the concave surface, the lower edge of the first conical surface defining a contact line separably contacting with the concave surface, a second conical surface adjacent to the first surface and having a conical angle substantially equal to that of the concave surface, a third conical surface adjacent to the second surface and having a conical angle greater than that of the concave surface. In case of a smaller lift amount of the needle valve, the fuel flow speed flowing into the fuel injection hole is fast and the atomized fuel injection divergence angle from the injection hole is great, thereby producing active producing mixing of the fuel with the air and enhancing the ignition feature, while in case of a greater lift amount, the fuel flow speed is slow and the atomized fuel injection divergence angle from the injection hole is small, thereby increasing the fuel flow reach and producing an active mixing of the fuel with the air by virtue of the kinetic energy of the atomized fuel flow.

摘要： The fuel injection apparatus of the invention comprises a unit injector for injecting fuel to a combustion chamber of an internal combustion engine. An injection pump chamber and a timing chamber are defined in the unit injector, a quantity of fuel, adjusted in accordance with a drive condition of an engine, being supplied to these chambers. Fuel in the injection pump chamber and the timing chamber can be pressurized by an injection plunger and a timing plunger operated by pressure from the same pressure source. When the fuel in the injection pump chamber is pressurized to a predetermined injection pressure, fuel in the injection pump chamber is injected to the corresponding combustion chamber of the engine. The timing chamber is connected to a relief path, and a check valve, which can be opened at a pressure lower than the injection pressure, is provided in the relief path.

摘要： A variable-length encoding device includes a shift register for converting a binary data string representing an audio signal into unit words of three 2-bit data (e.g., (1,1), (1,0), and (0,1) and two 3-bit data (e.g., (0,0,0) and (0,0,1). The 3-bit data words are obtained such that the remaining 2-bit data (i.e., (0,0)) is used as upper two bits of each of the resultant 3-bit data and is combined with each of the "1" and "0" data of the resultant 3-bit data. The output data words from the shift register are converted by a logic circuit to the corresponding code words in one-to-one correspondence. Each code word has a bit number twice that of the input data word. If a bit array (1,0,1) is included in the code word bit stream thus obtained, this bit array is further converted to (0,0,1).
