VALVE JET PRINTER WITH INERT PLUNGER TIP |
摘要 |
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. |
