摘要： An object of the invention is to provide a depressurizing valve mounted to a common rail for a fuel injection device, in which a direction of a connector for the depressurizing valve can be adjusted, without affecting an air gap and a sealing performance. The depressurizing valve has a valve unit and a coil unit which is detachably assembled to the valve unit by a mounting member, such as a retaining nut. A valve housing has an inside space, which is fluid tightly separated into first and second spaces by a connecting member, which is fluid tightly connected to the valve housing and a stator core. A valve body and a spring are arranged in the first space for closing a flow control port. A cylindrical coil is accommodated in the second space, such that the coil is rotatable with respect to the valve housing.

摘要： A solenoid valve includes a coil, a stator core, a valve member, a coil spring, and a stopper. The coil provides a magnetic field when the coil is energized. The stator core includes a receiving bore, wherein the stator core generates a magnetic attractive force when the coil is energized. The valve member is attracted toward the stator core due to the magnetic attractive force generated by the stator core. The coil spring is received in the receiving bore of the stator core, wherein the coil spring biases the valve member in an opposite direction opposite from the stator core. The stopper positions the coil spring such that an outer peripheral surface of the coil spring is separated from an inner peripheral surface of the receiving bore.

摘要： An electromagnetic actuator includes a cylindrical coil, a stator core disposed in the cylindrical coil, a plate attached to one axial end of the stator core and an armature positioned to face the other axial end of the stator core. Upon energizing the coil, the armature is attracted to the stator core against a biasing force of a spring disposed in an inner space of the stator core. A depressed portion is formed on the plate and/or the stator core to suppress a magnetic flux passing therethrough and to reduce an amount of leakage flux. The magnetic flux generated by the coil is effectively used to drive the armature, and thereby a response time of the actuator is shortened. In other words, the armature is quickly driven upon energizing the coil.
摘要翻译：电磁致动器包括圆柱形线圈，设置在圆柱形线圈中的定子芯，附接到定子芯的一个轴向端的板和定位成面向定子芯的另一个轴向端的衔铁。在使线圈通电时，电枢克服设置在定子芯的内部空间中的弹簧的偏置力而被吸引到定子芯。在板和/或定子铁芯上形成凹陷部分，以抑制通过其的磁通量并减少漏磁通量。线圈产生的磁通有效地用于驱动电枢，从而缩短致动器的响应时间。换句话说，在对线圈通电时，电枢被快速地驱动。
