INKJET NOZZLE DEVICE HAVING CHAMBER GEOMETRY CONFIGURED FOR CONSTRAINED SYMMETRIC BUBBLE EXPANSION

摘要

An inkjet nozzle device is configured for constrained symmetric bubble expansion. The inkjet nozzle device includes a firing chamber having a nozzle aperture and a heater element. The heater element extends between an end wall of the firing chamber and a baffle plate facing the end wall. The baffle plate is wider than the heater element and a centroid of the heater element coincides with a midpoint between the baffle plate and the end wall.
