    • A high flow rate electromagnetic injector valve with a rapid response time and a method for calibrating such injector is disclosed for utilization in a single point fuel injection system. Centrally bored end caps are fixed at the front and rear ends of a tubular injector body and a coil wound on a bobbin is disposed inside the body chamber between the end caps. The front end cap receives within its bore a valve assembly including a valve housing and a needle valve with attached armature reciprocally movable against a valve seat to obturate a metering orifice in the valve housing. The valve housing contains fuel inlets for the pressurized entry of fuel into the injector and the needle valve is ported to provide fluid communication to the armature to relieve pressure build-up. The rear end cap mounts within its bore a core member acting as a stator which extends through a central bobbin bore to form a controllable air gap adjacent the armature, the core member further contains internally an adjustment screw and ball member. The ball member and adjustment screw cooperate with a recessed closure spring positioned substantially within the armature to controllably bias the needle valve against the valve seat. By the adjustment of the core member and the adjustment screw both the static fuel flow and the dynamic fuel flow of the injector are respectively calibrated.
    • 公开了具有快速响应时间的高流量电磁喷射阀和用于校准这种喷射器的方法,以用于单点燃料喷射系统。 中心钻孔端盖固定在管状喷射器主体的前端和后端,并且缠绕在线轴上的线圈设置在端盖之间的主体室内。 前端盖在其孔内容纳有包括阀壳体和针阀的阀组件,其具有可相对于阀座往复移动的附接电枢,以堵塞阀壳体中的计量孔。 阀壳体包含用于加压进入喷射器的燃料入口,并且针阀被移入以提供与电枢的流体连通以减轻压力积聚。 后端盖在其孔内安装有用作定子的芯构件,该芯构件延伸穿过中心骨架孔以形成邻近衔铁的可控气隙,所述芯构件还内部包含调节螺钉和球构件。 球构件和调节螺钉与基本上位于衔铁内的凹入的闭合弹簧配合,以可控制地将针阀偏压抵靠阀座。 通过调节芯部件和调节螺钉,分别校准喷射器的静态燃料流量和动态燃料流量。

    • An interspinous process spacer insertion device that positions an interspinous process spacer between the spinous process of adjacent vertebrae in a minimally invasive percutaneous surgical procedure. The device includes a trocar rod that extends through a cannulated sleeve. The spacer is attached to the end of the cannulated sleeve, where a trocar tip of the trocar rod extends through the spacer. The trocar rod is moved through the cannulated sleeve and an incision in the patient, and is positioned between the spinous process of the vertebra to align the device. The cannulated sleeve is then moved down the trocar rod so that the spacer slides between the spinous process, and the trocar rod is then withdrawn from the patient. The spacer is then rotated so that it locks behind the spinous process, and the cannulated sleeve is detached from the spacer and removed from the patient.
    • 棘突间间隔插入装置,其在微创经皮外科手术中将棘突间间隔物定位在相邻椎骨的棘突之间。 该装置包括穿过套管的套管针杆。 间隔件附接到套管套筒的端部,套管针杆的套管针尖延伸穿过间隔件。 套管针杆通过套管套管和患者的切口移动,并且位于椎骨的棘突之间以对准装置。 然后将套管套筒向下移动套管针杆,使得间隔件在棘突之间滑动,然后将套管针杆从患者身体中取出。 然后将间隔物旋转,使其锁定在棘突的后面,并且将套管套筒与间隔物分离并从患者身上取出。
