Abstract

One method for rapidly starting and stopping a continuous-flow ink jet nozzle is to cover the nozzle orifice with a slider valve. The valve must make good contact with the nozzle plate surface and must move rapidly (probably in excess of 250 centimeters per second) over the nozzle orifice. Covering long arrays of nozzles is particularly difficult because of slight surface variations along the length of the nozzle array. Shown above in Figs. 1 and 2 is a segmented slider valve 10 for covering nozzles 12 in nozzle plate 14.
