DEVICE FOR DEPOSITING DROPS Russian patent published in 2008 - IPC B41J2/14 

FIELD: technological processes, typography.

SUBSTANCE: method for making components for jet printing head consists of the following stages: making case, with upper surface, making several apertures in the indicated upper surface, passing into the case, and an actuating structure inside each of the apertures. Each actuating structure remains fixed to the body frame during operation. The actuating component for the jet printer with formation of drops under request, has a case with an upper surface, an aperture in the upper surface, passing into the case along the axis of the aperture, a convex actuating structure inside the aperture, and electrodes, which are positioned such that, they can apply a field to the actuating structure in such a way that, the actuating structure is deformed. Electrical voltages applied to the walls do not give rise to deviation of the walls and emission of drops through the nozzle.

EFFECT: fast propulsion, without loss of accuracy and piezoelectric material settles uniformly, actuating mechanisms have same channel separation along matrix.
