Abstract: A valve jet printer includes a solenoid coil and a plunger rod having a magnetically susceptible shank. A first end of the shank and at least a portion of the shank are received within a bore of the solenoid coil. The printer also includes a nozzle including an orifice extending therethrough and a spring biasing a second end of the shank toward the nozzle. The second end of the plunger rod includes a tip formed of perfluoroelastomer (FFKM). The second end of the shank includes a cup-shaped cavity having a convex bottom and a circular side. The tip includes a concave base and an annular flange. In an assembled state, the concave base of the tip contacts the convex bottom of the cup-shaped cavity, and the end of the circular side opposite the convex bottom is rolled over the annular flange thereby securing the tip in the cup-shaped cavity.

Abstract translation: 阀喷射打印机包括螺线管线圈和具有磁敏感柄的柱塞杆。 杆的第一端和柄的至少一部分被容纳在螺线管线圈的孔内。 打印机还包括喷嘴，其包括延伸穿过其中的孔口以及将柄部的第二端朝向喷嘴偏置的弹簧。 柱塞杆的第二端包括由全氟弹性体（FFKM）形成的尖端。 柄的第二端包括具有凸底和圆形侧的杯形腔。 尖端包括凹形基部和环形凸缘。 在组装状态下，尖端的凹形底部接触杯形腔的凸形底部，并且与凸起底部相对的圆形侧的端部在环形凸缘上滚动，从而将尖端固定在杯形腔中。
