    • A controller for an automatic transmission which reduces wear of frictional engagement elements and shortens gear change time even when a gear change jump is made. The controller of the present invention includes a first hydraulic servo to which oil is supplied to make a gear change jump, a second hydraulic servo to which oil is supplied to make a gear change to an intermediate gear stage, a limited supply oil circuit having an oil flow limiting element, a quick supply oil circuit bypassing the oil flow limiting element and a pressure governor for regulating a line pressure to supply oil at a controlled pressure to the quick supply oil circuit. An oil path switching valve switches oil supply, to the first hydraulic servo or the second hydraulic servo, between the limited supply oil circuit and the quick supply oil circuit. Accordingly, when a gear change jump is made, oil is supplied to the first hydraulic servo via the quick supply oil circuit and the operating pressure can be increased quickly, so that the gear change time is shortened.
    • 一种用于自动变速器的控制器,其减少摩擦接合元件的磨损,并且即使在进行变速跳变时也缩短变速时间。 本发明的控制器包括:第一液压伺服机构,供给油以进行齿轮变速跳闸;第二液压伺服机构,供油供变速换档到中间齿轮级;有限供油回路,其具有 油流量限制元件,绕过油流限制元件的快速供油回路和用于调节管路压力的压力调节器,以将控制压力的油供应到快速供油回路。 油路切换阀在有限供油回路和快速供油回路之间切换供油到第一液压伺服或第二液压伺服。 因此,当进行变速跳跃时,通过快速供油回路向第一液压伺服机构供给油,能够快速地提高作业压力,缩短变速时间。

    • A fuel injector for injecting fuel into a combustion chamber of internal combustion engine with an injection flow rate that changes during an injection cycle. It provides a gradual increase in fuel injection rate near the beginning of the cycle and a substantially instantaneous shut off of fuel injection at the end of the cycle. The valve includes a nozzle body with a fuel inlet and a nozzle portion which has an injection port therein, a first fuel passage for communicating the injection port with the fuel inlet, a first slidable needle valve element, a first spring for urging the first needle valve element to close the first needle valve element, a second fuel passage for communicating a back pressure chamber with the fuel inlet, an ON-OFF valve for opening and closing the second fuel passage and throttling the effective area thereof when the second fuel passage is open thereby controlling the pressure of the first back pressure chamber means.
    • 一种用于将燃料喷射到内燃机的燃烧室中的燃料喷射器,其具有在喷射循环期间改变的喷射流量。 它在循环开始附近提供燃料喷射率的逐渐增加,并且在循环结束时基本上瞬间关闭燃料喷射。 该阀包括具有燃料入口的喷嘴主体和在其中具有喷射口的喷嘴部分,用于使喷射口与燃料入口连通的第一燃料通道,第一可滑动针阀元件,用于推动第一针 阀元件以关闭第一针阀元件,用于使后压室与燃料入口连通的第二燃料通道,用于打开和关闭第二燃料通道并且当第二燃料通道为有效区域时节流其有效区域的开关阀 打开,从而控制第一背压室装置的压力。
