Abstract
The invention relates to a rotary sprayer for spraying a coating material, comprising a fixed body, a spraying member, a device for rotating the spraying member about a rotational axis, and a flow path for supplying the spraying member with a coating material. The spraying member for the coating material includes a flow surface for receiving the coating material and an edge for spraying the coating material. The rotary sprayer further includes a device for injecting air into a region located radially inside the space defined by the flow surface and upstream from the edge, the air-injecting device being separate from the coating material supply flow path. The air-injecting device includes an air dispenser arranged in an upstream portion of the flow surface, which injects air into a central area of the surface.
