Zusammenfassung: | To provide a spray gun that can be adjusted to a spraying pattern based on a size and a surface shape of a painted article, and paint-liquid characteristics.SOLUTION: A spray gun is provided for atomizing liquid by the compressed gas. The spray gun has a gas cap 6 for injecting the compressed gas and a liquid nozzle 4 for injecting the liquid. The gas cap 6 has: a central gas passage 20 provided with an opening 51 in the vicinity of the liquid nozzle 4; and multiple pairs of side gas ports (65, 66) provided toward the center of the injection direction of the liquid nozzle 4 being the outside of the opening 51 and the symmetrical position across the center of the liquid nozzle 4. The gas pressure of the side gas ports (65, 66) is individually controlled every pair of the side gas ports (65, 66).SELECTED DRAWING: Figure 3
【課題】被塗物の大きさ、表面形状及び塗布する液体の特性等に応じた噴霧パターンに調整することができるスプレーガンを提供する。【解決手段】圧縮気体で液体を霧化するスプレーガンであって、圧縮気体を噴射する気体キャップ6と、液体を噴射する液体ノズル4と、を有し、気体キャップ6が、液体ノズル4の近傍に開口51が設けられた中心気体流路20と、開口51の外側であって、液体ノズル4の中心を挟んだ対称位置に液体ノズル4の噴射方向の中心に向けて設けられた側面気体口(65、66)の複数の対と、を有し、側面気体口(65、66)の気体の圧力を側面気体口(65、66)の対ごとに個別に制御する、スプレーガンを提供する。【選択図】図3 |
