摘要:
A color change valve device (11) comprises a manifold (12) an inside of which forms a paint passage (13), and to which connector passages (12B) are provided to radially penetrate therethrough at plural locations axially spaced from each other, a wash air valve (16) and a wash liquid valve (17) provided to be connected to the connector passages (12B) at the most upstream side among the respective connector passages (12B) in the manifold (12), and paint valves (18 to 23) of color A to color F provided to be connected to the connector passages (12B) in the manifold (12) to be positioned at the downstream side of the respective valves (16), (17). A swirl flow forming member (24) is provided in the paint passage (13) in the manifold (12) for forming a swirl flow by the wash air and the wash liquid, wherein the swirl flow forming member (24) is arranged across an entire length of the paint passage (13).
