HEAD OF LIQUID EJECTION AND METHOD OF LIQUID EJECTION Russian patent published in 2011 - IPC B41J2/175 

FIELD: printing industry.

SUBSTANCE: head of liquid ejection is proposed, for printing on paper carriers. Head of liquid ejection, comprising the following components: exhaust channel, through which the liquid is ejected; channel, which is connected to exhaust channel; and energy-generating element, which is arranged in the channel and generates energy used for ejection of liquid from exhaust channel. Besides, the channel comprises the first inlet track supplying liquid into energy-generating element; the second inlet track supplying liquid into energy-generating element in direction opposite to direction, in which the first inlet track supplies liquid; and outlet track providing for ejection of liquid supplied into energy-generating element.

EFFECT: liquid ejection head may reduce inclination of liquid ejection direction and thus reduce change in position of effect, even when ink is ejected during circulation.
