Abstract

A device and a hydrodynamic nozzle for a generation of a high pressure pulsating jet of a liquid without cavitation and saturated vapour The device for the adjustment of surfaces and dividing of materials with the hydrodynamic nozzle for the generation of high pressure pulsating jet of liquid without cavitation and presence of saturated vapours. The device for adjustment of surfaces and dividing of materials with the hydrodynamic nozzle generates pulsating jet, which is able to perform a very effective cleaning or removing surfaces of materials or dividing the given bodies of materials. The device could be composed of the bearing body (2) and the body of nozzle (1), which are mutually sealed by the sealing (3). The hydrodynamic nozzle, which consists of input openings (22) of oscillatory chamber (20), the oscillatory chamber (20) and the output neck (21), allows constructing a very small, effective and reliable device for the cleaning of surfaces, removing of surfaces and for dividing of materials by pressure liquid. A high efficiency and reliability is also achieved, because in the whole device, in the input opening of device (25), in the input channel (24), in the relief opening and in others parts it does not come to the formation of cavitation or to the formation of saturated vapours, even at a very high operating power supply pressures.
