摘要： A two-position, three-way solenoid-actuated valve includes a valve assembly having an axial opening and a valve member fixed in the axial opening with a first valve seat and a second valve seat disposed in the axial opening. The valve assembly including a ball disposed in the axial opening and moveable between the first valve seat and the second valve seat. The two-position, three-way solenoid-actuated valve also includes an electromagnetic coil assembly engaging the valve assembly to move the ball between the first valve seat and the second valve seat to open and close a fluid path through the valve assembly to provide directional flow control.

摘要： A uniformly preset spring force pre-load among a number of identical solenoid actuated valve assemblies (28) by uniquely adjusting the spring pocket length (L) of each respective plunger (12) to accommodate a respective spring (20) which is uniquely mated thereto. This adjustment is accomplished using a two-component plunger (12) consisting of a plunger body (14) having a central bore (22) and a rod (18) slidably located within the central bore. The rod (18) is press-fit into the central bore (22), and the spring pocket includes a portion of the central bore unoccupied by the rod. By pressing the rod (18) a selected distance into the central bore (22), a precisely set spring pocket is obtained which is uniquely correct for a selected spring (20), in that the selected spring is compressed to a precisely preset spring force pre-load. The adjusted plunger (12) and spring (20) are uniquely assigned to each other to collectively form a customized plunger assembly (10) having a preset spring force pre-load, whereupon a valve assembly (28) is manufacturable therewith having the precisely preset spring force pre-load. In carrying-out the adjustment of the plunger (12) with respect to a specific spring (20), the rod is pressed into the bore by a controllable source of force, such as for example provided by a stepper motor (88), and the spring force pre-load is monitored by a load cell (78) to ascertain when the desired spring force pre-load is achieved. Monitoring and force control is preferably automatic via a micro-controller (98), but may be manual.
摘要翻译：通过唯一地调节每个相应的柱塞（12）的弹簧袋长度（L）以容纳与其唯一配合的相应的弹簧（20），在多个相同的电磁致动阀组件（28）中均匀地预设弹簧力预加载。这种调整使用由具有中心孔（22）的柱塞体（14）和可滑动地位于中心孔内的杆（18）组成的双组分柱塞（12）来完成。杆（18）压配合到中心孔（22）中，并且弹簧袋包括不被杆占据的中心孔的一部分。通过将杆（18）按压到中心孔（22）中的选定距离，获得精确设定的弹簧袋，其对于所选择的弹簧（20）是唯一正确的，因为所选择的弹簧被压缩到精确预设的弹簧力预加载。经调节的柱塞（12）和弹簧（20）被独特地分配给彼此，以共同形成具有预设弹簧力预加载的定制的柱塞组件（10），于是可以制造具有精确预设的阀组件（28）弹簧力预加载。在相对于特定弹簧（20）执行柱塞（12）的调节时，杆通过可控的力例如例如由步进电动机（88）提供而被压入孔中，并且弹簧力预加载由测力传感器（78）监测，以确定何时实现期望的弹簧力预加载。监视和力控制优选地通过微控制器（98）自动进行，但是可以是手动的。
