FIELD: engines and pumps.
SUBSTANCE: invention relates to a liquid discharge device and a liquid discharge head, which perform liquid discharge. Common feed channel is connected to one end of the outlet module with outlet nozzle, which discharges the liquid, and the common discharge channel is connected to the other end of the outlet module. In the adjustment channel there is a valve connecting the common feed channel and the common discharge channel and opening at the first opening pressure. Pump causes fluid flow from common supply channel towards common discharge channel. Resistance of common drain channel flow is less than outlet module flow resistance.
EFFECT: disclosed are a liquid discharge device and a liquid discharge head.
