    • The fuel in a compression pump chamber, defined by a compression plunger, is expelled by the compression plunger driven synchronously with the rotation of an engine. An injection plunger is driven by the expelled fuel, thus injecting fuel into an injection pump chamber defined by the injection plunger. A timing passage, closed by the compression plunger, is formed in the compression pump chamber, and a metering passage is formed in the injection pump chamber. The timing and metering passages communicate with a timing valve and a quantity control valve respectively arranged in an electromagnetic valve. The timing and quantity control valves are driven by an energization current such that they operate in cooperation with each other, i.e., when the timing valve is open, the quantity control valve is closed. When the timing valve is closed and the compression plunger returns, the injection plunger also returns and fuel is supplied to the injection pump chamber through the quantity control valve, which is open. The quantity of fuel filled in the injection pump chamber is controlled by the time interval during which the quantity control valve is open. The time interval during which the fuel is supplied to the pump chamber through the quantity control valve is calculated so as to correspond with engine conditions.
    • 由压缩柱塞限定的压缩泵室中的燃料由与发动机的旋转同步地驱动的压缩柱塞排出。 注射柱塞由排出的燃料驱动,从而将燃料喷射到由注射柱塞限定的注射泵室中。 由压缩柱塞闭合的定时通道形成在压缩泵室中,并且在喷射泵室中形成计量通道。 定时和计量通道与分别布置在电磁阀中的定时阀和量控制阀相通。 定时和数量控制阀由通电电流驱动,使得它们彼此协作地操作,即当定时阀打开时,量控制阀关闭。 当定时阀关闭并且压缩柱塞返回时,喷射柱塞也返回,并且通过打开的量控制阀将燃料供给到喷射泵室。 填充在喷射泵室中的燃料量由量控制阀打开的时间间隔来控制。 计算通过量控制阀将燃料供应到泵室的时间间隔,以便与发动机条件相对应。

    • 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.
    • 本发明的燃料喷射喷嘴在主体中具有蓄积室,其中使用止回阀将从燃料喷射泵供给的高压燃料储存在该主体中。 在阀体中设置有针阀,以将燃料喷射到积聚室中。 针阀的喷嘴针和阀构件被同轴地并排配置。 喷嘴针和阀构件的彼此相邻的端部被可滑动地和液密地装配在一起,以在阀构件和喷嘴针之间限定阻尼室。 此外,阻尼柱塞同轴地装配到阀构件中。 将阻尼室与燃料喷射泵的一侧连接的通道同时形成在阻尼柱塞中并具有减小的面积。

    • 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.
    • 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。
