ROTOR GENERATOR OF ELASTIC VIBRATIONS Russian patent published in 2001 - IPC

FIELD: acoustic engineering, applicable for identification of mass transfer processes. SUBSTANCE: the rotor generator of elastic vibrations has coaxial hollow rotor and stator made in the form of a cone (axial type truncated cone) with holes in their side walls. The cross-section of the outlet and inlet holes represents a trapezoid, whose lateral sides are positioned in the generating line of the lateral surfaces of the rotor and stator and intersect in one point. EFFECT: enhanced intensity of vibrations due to the matching of the shape of section of the holes and the shape of the lateral surface of the rotor and stator. 2 dwg
