摘要： A fuel injection nozzle of the present invention has an accumulating chamber in a body in which high pressure fuel fed from the fuel injection pump is stored using a non-return valve. A needle valve is arranged in the body to inject the fuel in the accumulating chamber. A nozzle needle of the needle valve and a valve member are arranged coaxially and in series with each other. Those end portions of the nozzle needle and valve member which are adjacent to each other are slidably and liquid-sealingly fitted together to define a damping chamber between the valve member and the nozzle needle. Further, a damping plunger is coaxially fitted into the valve member. A passage which connects the damping chamber with the side of the fuel injection pump is coaxially formed in the damping plunger and has a reduced area.

摘要： A fuel injection nozzle of this invention includes a nozzle housing which defines therein a fuel sump chamber, stepped cylinder bore and fuel passage connected at one end to the sump chamber and at the other end to a smaller diameter bore section of a stepped bore. A stepped plunger is fitted into the stepped cylinder bore to define a pump chamber communicating with the fuel passage and a main fuel chamber into which the main fuel is supplied from a fuel injection pump. An auxiliary fuel is supplied from a feed pump through the fuel passage into the sump chamber and pump chamber. A nozzle needle is located within the nozzle housing and is responsive to a fuel pressure within the sump chamber to cause it to be lifted to permit an injection hole to be opened. The nozzle needle is urged under a predetermined force of a pressure spring in a direction in which the injection hole is blocked. The urging force of the pressure spring is set to be greater than the pressure of the auxiliary fuel supplied from the feed pump and smaller than the pressure of the main fuel supplied from the fuel injection pump. The main fuel chamber, when the plunger is moved a predetermined distance responsive to the fuel pressure within the main fuel chamber, is permitted to be connected to the fuel passage.
摘要翻译：本发明的燃料喷嘴包括喷嘴壳体，其在其中限定有燃料油槽室，阶梯式气缸孔和燃料通道，其一端连接到集油室，另一端连接到阶梯式孔的较小直径的孔部分。阶梯式柱塞装配到阶梯式气缸孔中以限定与燃料通道连通的泵室和从燃料喷射泵供应主燃料的主燃料室。辅助燃料从进料泵通过燃料通道供应到贮槽室和泵室中。喷嘴针位于喷嘴壳体内，并且响应于贮槽室内的燃料压力以使其被提升以允许打开喷射孔。喷嘴针在压力弹簧的预定力的作用下沿喷射孔被阻挡的方向被推压。压力弹簧的推压力被设定为大于从供给泵供给的辅助燃料的压力，并且小于从燃料喷射泵供给的主燃料的压力。主燃料室当柱塞相对于主燃料室内的燃料压力移动预定距离时被允许连接到燃料通道。

摘要： A sweep voltage from a sweep voltage generator is provided to sweep start and stop adjusting means, the outputs of which are summed by a summing circuit and, by the summed output, the oscillation frequency of a voltage controller oscillator is controlled. The oscillation frequency of the voltage controlled oscillator and the output frequency of a reference signal generator set to a sweep start frequency are compared by comparing means. The output of the sweep voltage generator is put in a sweep start state and sweep start adjusting means is adjusted in accordance with the output of the comparing means, thereby to cause the oscillation frequency of the voltage controlled oscillator to agree with a set sweep start frequency. The output of the sweep voltage generator is put in a sweep stop state and sweep stop adjusting means is adjusted in accordance with the output of the comparing means, thereby to cause the oscillation frequency of the voltage controlled oscillator to agree with a set sweep stop frequency.

摘要： A noise wave is received by a receiver and the received output is supplied to a first signal path composed of a rectifier and a low-pass filter connected to the output side thereof. The received output is applied to a second signal path comprised of an AC amplifier, or a rectifier for rectifying the amplified output, a low-pass filter for filtering the rectified output, and an attenuator for attenuating the filtered output. The outputs from the first and second signal paths are selectively provided to a time constant circuit by means of a switch in accordance with the received noise level. The input to the time constant circuit is converted into a quasi-peak value detected output, which is logarithmically amplified by a logarithmic amplifier and is then provided to an indicator.

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.
