ABSTRACT:
Devices for cleaning of enclosed spaces by means of liquid sprayed out. The device comprises a housing with a stationary part to which the liquid is supplied and on which a rotatable part bearing a hub is mounted. The hub has at least one spray nozzle. An element suspends the hub in a bearing in the rotatable part. The rotatable part comprises a turbine driven by the liquid and having a planetary gear for turning the rotatable part and at least one nozzle so that the liquid sprayed out by at least one of the nozzles during rotation sweeps across the inside of the enclosed spaces. The stationary part comprises an upper ring gear in engagement with a lower ring gear on the hub, which two ring gears are surrounded by the housing. The turbine and the planetary gear are fitted in the rotatable part to achieve a compact device.
