Abstract
A nozzle head comprises a plurality of nozzles, a nozzle carrier rotatable about an axis and driveable by a reaction of a pressurized water discharged from the nozzles, a stationary housing, a hollow shaft extending through the housing and having a central passage, a sleeve extending through the central passage of the hollow shaft, the sleeve forming a supply conduit and extending to the region of the nozzle carrier. The sleeve has a free end which is closed and a transverse opening which opens into the supply conduit, the nozzle carrier having a plurality of passages extending from the transverse opening to the nozzles for supplying pressurized water, and the nozzles being arranged so that water jets discharged from the nozzles are interrupted into edge regions of a jet curve parallel to a displacement direction of the nozzle head relative to an object.
