FLUID JETTING HEAD AND FLUID JETTING DEVICE

摘要

A fluid jetting head capable of preventing crosstalk from occurring and providing stable fluid jetting characteristics and a fluid jetting device, the fluid jetting head wherein partition walls (11) on the lateral both sides of pressure generating chambers (12) are extended near the pressure generating chamber (12) side end part of a reservoir part (32), and fluid supply passages (14) formed to have a width smaller than the width of the pressure generating chambers (12) in communication with the pressure generating chambers (12) and communication passages (100) allowing the fluid supply passages (14) to communicate with a communication part (13) and formed to have a width larger than the width of the fluid supply passages (14) are provided by dividing each of the pressure generating chambers (12) by the partition walls (11) (wall parts 11a). Thus, the occurrence of the crosstalk can be prevented and the stable fluid jetting characteristics can be provided.
