Ink Jet Nozzle Assembly

Ink jet nozzles can be constructed with improved control of adhesive flow by providing pressure relief slots during assembly.

Referring to the figure, orifice plate 1 and adapter 2 are first joined by a seal glass preform 3 as a nozzle subassembly. The subassembly is placed within hollow boss 4 of ink manifold 5 upon a layer of adhesive on surface 6. Several slots 7 are formed in the wall of the hollow boss to allow excess adhesive to flow from the junction of the subassembly and surface 6 during placement and curing of the adhesive.

This technique provides a uniform layer of adhesive at the junction and reduces the chance of having excess adhesive flow onto the orifice plate 1. The transparency of the nozzle subassembly enables inspection of the orifice plate, however, to detect excess adhesive on the plate, if present, due to accidental jarring.
