发明名称 LIQUID EJECTING HEAD, LIQUID EJECTING HEAD UNIT, AND LIQUID EJECTING APPARATUS
摘要 A liquid ejecting head includes nozzles for ejecting liquid; pressure generation chambers, each in fluid communication with one of the nozzles; and a manifold substrate with manifolds disposed therein. Each manifold supplies liquid to at least one of the pressure generation chambers. The liquid ejecting head also includes a head case with a piezoelectric element housing unit. Piezoelectric elements, for changing pressure of liquid within the pressure generation chambers, are provided in the piezoelectric element housing unit. The liquid ejecting head also includes a vibrating element for absorbing pressure changes in the liquid within the manifolds, cavities provided on the vibrating element at positions that correspond to positions of the manifolds, and an atmosphere exposure channel that fluidly connects one of the cavities to the atmosphere. At least one other one of the cavities is in fluid communication with the atmosphere exposure channel via the first cavity.
