Abstract

The figures illustrate an ink gun with an orifice inside the plunger of the gun. Typically, when an ink gun is closed by pushing a plunger against a nozzle, the gun spits if the plunger rod is closed with too much force or drips if not enough force is used. An improved ink dispense gun solves this problem by including an orifice inside the plunger. The amount of force used is not important.

Improved Ink Dispense Gun

      The figures illustrate an ink gun with an orifice inside the
plunger of the gun.  Typically, when an ink gun is closed by pushing
a plunger against a nozzle, the gun spits if the plunger rod is
closed with too much force or drips if not enough force is used.  An
improved ink dispense gun solves this problem by including an orifice
inside the plunger. The amount of force used is not important.

      Fig. 1 is a cross sectional view of the "T" orifice gun.  Ink
flows in at an inlet 1 continuously through the gun and out at outlet
3.  The ink flows out of an orifice 2 when a plunger rod 4 is
retracted.  Fig. 2 shows the on and off positions.  The plunger is
actuated with an air cylinder.  This design provides an ink flow with
constant pressure without an ink surge during the gun shut-off.
