Abstract (en)
[origin: EP0972503A2] The feed device has an electric motor driving a rotor wheel (19) which extracts water from the interior of the bath via suction openings (11) in a suction rosette (42) , before injecting the water back into the bath as a jet via centrral discharge openings (3a), with an air channel (38) alowing air to be mixed with the injected water. The air channel contains a non-return device for blocking ingress of water when the rotor wheel is switched off.
