    • An injector has a lift limiting member provided by a single plate member. The plate member has a stopper face, multiple hole sections, a flow passage hole, and a spring seat face. An axial end face of a needle head section of a needle contacts the stopper face when the needle lifts by a predetermined amount. Transmitting sections of a pressurizing piston are loosely inserted in the hole sections. High pressure fuel can pass through the flow passage hole. The spring seat face receives an end portion of a spring that biases the needle in a valve closing direction. The lift limiting member limits a valve opening lift position of the needle, so a stable injection quantity is obtained. Thus, a surface area of the single plate member can be used in multiple functions.
    • 注射器具有由单个板构件提供的升力限制构件。 板构件具有止动面,多个孔部,流路孔和弹簧座面。 当针提起预定量时,针头针头部分的轴向端面接触止动面。 加压活塞的传送部分松动地插入孔部分。 高压燃料可以通过流通孔。 弹簧座面接收弹簧的端部,该弹簧使得阀沿关闭方向偏压。 升降限制部件限制针的开阀提升位置,从而获得稳定的喷射量。 因此,单板构件的表面积可以用于多种功能。

    • A fuel injection valve includes a valve body having a valve seat, a valve element adapted to sit on and leave a valve seat, a nozzle hole for the injection of fuel, and an electromagnetic drive section. A holding member surrounds and holds, on one end side thereof, at least a partial area of an opposite-to-nozzle-hole-side end face portion of the valve element. The holding member surrounds and holds, on an opposite end side thereof, a predetermined surface area of a constant position holding portion without being influenced by the pressure of fuel flowing through a fuel passage of the valve body and irrespective of movement of the valve element. An internal area of the holding member is shut off so as not to be influenced by the pressure of fuel present around the internal area.

    • An apparatus for evaluating the characteristics of a photosensitive drum for use in electrophotography including a rotatable photosensitive drum having characteristics to be measured, a charging portion and an exposure light source portion and the like respectively secured to portions adjacent to the photosensitive drum. The surface potential of the photosensitive drum, which is generated due to operation of the charging portion and the exposure light source portion or the like, is measured by a potential measuring probe which is, together with the charged portion and the exposure light source portion and the like, secured adjacent to a position of the photosensitive drum, at which light is applied at the shortest distance from the exposure light source portion. The photosensitive drum is moved along its lengthwise direction so that the surface potential of the photosensitive drum is measured by the potential measuring probe.

    • A piston can reciprocate in a piston guide cylinder in an axial direction and has a cavity on a piezo driver side thereof. If the piezo driver is energized, a tip of a projecting section of a pushing member pushes a bottom wall of the piston defining the cavity. If fuel pressure of a pressure control chamber increases via a pressurization chamber and a communication passage due to pressurization by the piston, a needle moves in a valve-opening direction against a first compression coil spring. Since the piston has the cavity, a movable mass of the piston is reduced while securing axial length of a sliding section. Thus, fuel leak from the sliding section between the piston and the piston guide cylinder can be suppressed, and an inertial resistance caused in the piston can be reduced.
    • 活塞可以沿着轴向在活塞导向圆筒中往复运动,并且在压电驱动器侧具有空腔。 如果压电驱动器通电,则推动构件的突出部分的尖端推动限定空腔的活塞的底壁。 如果压力控制室的燃料压力由于通过​​活塞的加压而经由加压室和连通通道而增加,则针沿着阀打开方向抵靠第一压缩螺旋弹簧移动。 由于活塞具有空腔,所以可以确保活塞的可移动质量,同时确保滑动部分的轴向长度。 因此,可以抑制从活塞和活塞引导筒之间的滑动部分的燃料泄漏,并且可以降低在活塞中产生的惯性阻力。
