MICROINJECTOR AND METHOD FOR ITS MANUFACTURE Russian patent published in 2000 - IPC

FIELD: jet printing operation. SUBSTANCE: two zones are created in structure of main working part of microinjector membrane. These zones are as follows: zone of metal film having good properties of transmitting widening and compression such as nickel film. Other zone is of organic film with good ability of widening and compression for example zone of polyamide film. Each of these two zones is used as means for transmitting impact action intended for forceful ejection of liquid in upward direction. Each zone is also used for quick and exact setting in initial position. It also functions as hinge for spreading (dissipation) and elimination of stress so as by this way to prevent deformation of membrane for example to prevent wrinkling of membrane. In addition, membrane possessing such fortified main working part can sustain loads and react well on external action during operation. In result injection characteristics can be substantially improved. EFFECT: higher efficiency. 17 cl, 19 dwg
