Abstract

A nozzle for hydrodynamic cleaning has a form form of a flow passage with a profile formed by an inlet confuser, a resonance chamber and a diffuser arranged in axial alignment and interconnected in series. The confuser and the diffuser are connected via the resonance chamber, which has a form of a flow-over lip. The ratio of the cross-sectional area at the confuser outlet and the cross-sectional area at the opening of the resonance chamber forming the flow-over lip is 1.5 to 10.0. The preferred ratio of the resonance chamber surface area and the cross-sectional area at the opening of the resonance chamber is 0.05 to 40.0. The diffuser can comprise means for additional supply of fluid, gas or particulates. Impact is performed through a fluid jet flowing from a nozzle of the working member in a fluid or a gaseous medium.
