HYDRAULIC CAVITATION GENERATOR Russian patent published in 1995 - IPC

FIELD: cleaning and damaging surfaces. SUBSTANCE: hydraulic generator has a housing provided with an additional processing stage interposed between the cylindrical part and diffuser. The shape of generatrix of the stage is differ from the shape of generatrix of the cylindric part. The additional processing stage can have convex curved generatrix. The additional stage can have concave curved generatrix. The additional stage has broken generatrix. The diameter of the inlet part of the additional stage can be less than diameter of the outlet part. The diameter of the inlet part of the additional stage can be grater than the diameter of its outlet part. The cylindrical part of the inner side of the housing is projected into the space of the additional processing stage. The face surface of the cylindric part has a cone angle equal to 180 deg. The hydraulic cavitation generator can be dismountable to afford setting the additional stage of a given shape. EFFECT: improved design. 8 cl, 12 dwg
