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.

摘要： An inkjet printhead chip includes a wafer substrate (12). A CMOS drive circuitry layer is positioned on the wafer substrate. A plurality of nozzle arrangements is positioned on the wafer substrate and the CMOS drive circuitry layer. Each nozzle arrangement includes nozzle chamber walls and a roof wall that define a nozzle chamber and an ink ejection port (35) defined in the roof wall. A micro-electromechanical actuator (14) is connected to the CMOS drive circuitry layer. The actuator has at least one movable member (14) that is positioned to act on ink in the nozzle chamber to eject the ink from the ink ejection port on receipt of a signal from the drive circuitry layer. The movable member is spaced between 2 microns and 15 microns from the CMOS drive circuitry layer.
