Abstract

PURPOSE:To give the function of checking the back flow of ink to a flow channel by laminating a back-flow checking plate provided with holes and constructing the flow channel bent at right angle. CONSTITUTION:A pressurizing chamber 21 is formed by fitting an electrostrictive vibrator 3 to a slender pipe 2 and is communicated, at one end of the slender pipe 2, with a lead-out pipe which, in its turn, is communicated with a nozzle. The other end of the slender pipe 2 is joined with the 1st back-flow checking plate 14 with a number of tiny orifices 15. On the top of the 1st back-flow checking plate 14 is laid the 2nd back-flow checking plate 16 with its larger elliptic orifices 17 than the orifices 15 placed on the latter, and further on the top of the 2nd back- flow checking plate 16 is laid the 3rd back-flow checking plate with its piercing orifices 19 overlapping the elliptic orifices 17.
