Abstract

PURPOSE:To equalize the injection characteristics of each single nozzle head even when the nozzle length l of each nozzle disperses more or less by a mechanism wherein a valve mechanism is formed in a branch device, and the pressure of ink supplied to each single nozzle head is adjusted. CONSTITUTION:This invention relates to an ink jet printing head with a plurality of nozzles. Pressure adjusting screws 8, pressure adjusting valves 9 and shield materials 10 for preventing the leakage of a liquid are mounted into a branch device 1, and the shield materials 10 and receiving screws 11 are fixed to a holding member 7. The inlets of pipe sections 3 are formed taperingly. According to constitution mentioned above, ink at fixed pressure in a liquid chamber 2 is supplied to each single nozzle head at the desired pressure respectively by adjusting the pressure adjusting screws 8, and the injection characteristics of all single nozzle heads can be equalized. This head can also apply to a head with a multinozzle plate 12 and a vibrator section 14 for exciting the liquid.
