Title (EN) FLUID JETTING HEAD AND FLUID JETTING DEVICE
(FR) TETE ET DISPOSITIF POUR LA DIFFUSION DE JET DE FLUIDE
(JA) 液体噴射ヘッド及び液体噴射装置
Abstract: front page image
(EN)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.
(FR)L'invention concerne une tête de diffusion de jet de fluide capable d'empêcher la diaphonie et assurant des caractéristiques de jet de fluide stables, et par ailleurs un dispositif de jet de fluide comportant cette tête. Des cloisons séparatrices (11) sur les deux côtés de chambres de pressurisation (12) s'étendent près de l'extrémité côté chambre (12) d'un réservoir (32), et des conduits d'alimentation de fluide (14) moins larges que les chambres (12) communiquent avec les chambres (12); enfin, il existe des conduits de communication (100), assurant la communication entre les conduits d'alimentation (14) et une unité de communication (13), plus larges que ces conduits d'alimentation (14), avec séparation de chaque chambre (12) par le biais des cloisons (11) (cloisons 11a). On peut ainsi empêcher la diaphonie et assurer des caractéristiques stables de jet de fluide.
(JA)クロストークの発生を防止でき且つ安定した液体吐出特性を得ることができる液体噴射ヘッド及び液体噴射装置を提供する。圧力発生室12の幅方向両側の隔壁11をリザーバ部32の圧力発生室12側の端部近傍まで延設し、圧力発生室12側に連通してその圧力発生室12の幅より小さい幅で形成された液体供給路14と、この液体供給路14と連通部13とを連通すると共に液体供給路14の幅より大きい幅で形成された連通路100とを隔壁11(壁部11a)により圧力発生室12毎に区画して設けることにより、クロストークの発生を防止でき、安定した液体吐出特性を得ることができる。
