ABSTRACT:
A water nozzle, particularly for dust suppressing for example at cutting rollers, has a housing with a central opening, a guiding sleeve received at least partially in the central opening of the housing and having an inner passage which is stepped in an axial direction, and a piston stepped in the axial direction and displaceable in the passage of the guiding sleeve to a position in which a narrow gap is formed between the piston and the guiding sleeve so as to prevent solid particles entrained in a flow of water from entering the nozzle. The piston is spring biased in a direction opposite to the direction of the flow of water, so that upon termination of the latter the piston dislodges the solid particles accumulated at the nozzle.
