Abstract: A rotary sprayer (10) for fluids (14), has a rotating disc (22), a drive (58) for the disc (22), and a supply device (28) for the application of fluid (14) onto the disc (22). The disc (22) has a distribution plane (30) for the fluid (14), and at least one opening (34) is provided in the distribution plane (30), via which a secondary flow (50) of the fluid (14) is separated from the main flow (48) to another plane (46). The disc (22) has a first spray edge (44) for spraying the working flow (52) of the fluid (14) and a second spray edge (54) for spraying the secondary flow (50) of the fluid (14). Since the main flow is divided into a secondary flow and a working flow, the effective amount of fluid that is used to moisten the workpiece can be reduced without having to therefore reduce the amount of fluid that is supplied e.g. via the pipe conduit. The formation of drops is thereby reliably prevented and a pipe conduit is used that has a cross-section of adequate size to prevent clogging.
