Rotary sprayer for discharging small amount of fluid onto work piece e.g. roller, has rotating disk defining one distribution plane with opening, where spray edge of disk is communicated with other plane for spraying secondary fluid flow

摘要

The sprayer has a supply device for transporting main fluid flow. A rotating disk (22) is driven by a drive unit to receive the main fluid flow from the supply device. The disk defines a distribution plane for the main fluid flow, and other distribution plane. The former plane is equipped with an opening (34) in which secondary fluid flow is separated from the main fluid flow for a passage to the latter plane. A spray edge of the disk is communicated with the former plane for spraying working flow, and other spray edge is communicated with latter plane for spraying the secondary fluid flow.
