Abstract: Device that includes a housing with a stationary part configured to receive liquid into the device and a rotatable part arranged with the stationary part. The rotatable part is rotatably arranged with a hub with at least one spray nozzle. In the housing there is an axis with one part connected to a rotation generating element in the housing and another part provided with threads forming a worm screw. The worm screw fits into the threads of an adjacent first gear wheel forming a worm gear. The worm gear transmits rotational force from the rotation generating element via the axis for rotating the hub and the rotatable part. The rotation generating element, the axis and the worm gear are arranged in a flow path for liquid passing through the device, whereby the bulk of the liquid flows through the worm gear in a direction towards at least one spray nozzle.

Abstract: A flushing device (1) includes a flush liquid pipe (6) arranged in an enclosed space (2) with at least one flush head (7) which is substantially rotatable about the longitudinal axis (A) of the flush liquid pipe, and a nozzle device (8) arranged on said flush head, being substantially rotatable about an axis (B) extending substantially transversely to the longitudinal axis of said flush liquid pipe, having one or more nozzles (9, 11) for the provision of one or more flush liquid streams (10, 12) directed substantially against the inside of the enclosed space for the cleaning thereof.

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.

Abstract: The present invention relates to a device for interior flushing of spaces in tanks or containers. At least one rotatable part (8) of a pipe (6, 8, 11) for the supply of flushing liquid (7) is provided in the space (2) and said rotatable part (8) has at least one flushing nozzle (9) for discharging jets (10) of flushing liquid. A driving or operating device (22) is provided to rotate said rotatable part (8) about a geometric rotation axis (R1A) and the flushing nozzle (9) about another geometric rotation axis (R2A). The driving device (22) is provided to be brought to rotate in opposite rotary directions (R1, R2) by reversing its rotary direction. A switch device (23) is provided to bring either said rotatable part (8) or the flushing nozzle (9) to rotate in dependence of the rotary direction (R1 or R2) of the driving device (22). A control device (48) is provided to control the driving device (22) to rotate in one or the opposite rotary direction (R1 or R2).
