    • A Diesel engine distributor-type injection pump has a vane pump (3) providing fuel under pressure to an injection pump system formed by two pistons (17) pressed towards each other by a cam track (26) to provide fuel under injection pressure to fuel injection plug connectors (28, 29) when the radial position of a duct (27) in the bore of the rotating shaft (2) matches a connecting duct (28) of a respective injection outlet. To provide for precise timing of fuel being injected, pressurized fuel is drained under control of a slider valve (FIG. 1: 38, 39; FIG. 2: 72, 74) connected through a communicating duct (32, 42, 71) to the slider valve. The slider valve is operated by a piezoelectric positioning element (FIG. 1: 61; FIG. 2: 76) which moves the spool (74, 39) of the slider valve; in one embodiment (FIG. 1), the piezoelectric element operates a piston (53) having a substantially larger diameter than the end faces of the spool (39) to provide for excursion amplification; in another embodiment (FIGS. 2, 4-8), the piezoelectric elements are bending elements and thus provide for larger excursion.
    • 柴油发动机分配器型喷射泵具有叶片泵(3),其将压力下的燃料提供给由通过凸轮轨道(26)彼此挤压的两个活塞(17)形成的喷射泵系统,以在喷射压力下向燃料提供燃料 当旋转轴(2)的孔中的管道(27)的径向位置与相应注射口的连接管道(28)匹配时,注射塞连接器(28,29)。 为了提供喷射的燃料的精确定时,在通过连通管道(32,42,71)连接的滑阀(图1:38,39;图2:72,74)的控制下,加压燃料排出到 滑阀。 滑阀由通过滑块阀芯(74,39)移动的压电定位元件(图1:61;图2:76)来操作。 在一个实施例(图1)中,压电元件操作具有比卷轴(39)的端面大得多的直径的活塞(53),以提供偏移放大; 在另一个实施例(图2,4-8)中,压电元件是弯曲元件,因此提供更大的偏移。

    • A piezo-electric control device is used to restrain movement of the armature of an electromagnet until the current through the exciter winding of the electromagnet has reached almost the maximum value. This causes the force applied to the armature to be the maximum force from the start of movement, so that the overall time required for movement of the armature from its starting to its end position is substantially decreased. Specifically, the piezo-electric control device is a column of discs having an axis perpendicular to the axis of movement of the armature. When electrical energy is applied to the column it expands in the axial direction causing a locking member mounted on its end to engage a stop member which is part of the armature. The locking member can either push the stop member against a further rigid stop or two columns can be used to clamp the stop member between them.
    • 压电控制装置用于抑制电磁铁的电枢的运动,直到通过电磁铁的励磁机绕组的电流达到最大值。 这导致施加到电枢的力是从运动开始起的最大力,使得电枢从其起始到其结束位置的运动所需的总体时间大大减小。 具体地,压电控制装置是具有垂直于电枢的运动轴线的轴的一列盘。 当电能施加到柱时,其在轴向方向上膨胀,使得安装在其端部上的锁定构件接合作为电枢的一部分的止动构件。 锁定构件可以推动止动构件抵抗另外的刚性止挡,或者可以使用两个柱来将止动构件夹在它们之间。
